I know this is a shot in the dark, but would love to see the D&D VTT on current gen consoles because it would allow my friends and I to play d&d together online when unable to in person. All of us currently have potatoes for computers and it would be a nice option to beable to run a game on console when we are unable to meet in person.

I can't see this happening. It'd be a lot of work for a niche demographic.

If you want a VTT that's light on the PC then Roll20 and AboveVTT are great options. They run on almost anything, even on mobile phones, use very little system resources and both integrate with D&D Beyond (Above VTT does this naturally while for Roll20 you can use the Beyond20 extension). 

If you play theatre of the mind and just need a place to chat and roll - there's Discord which can run off mobile phones as well and can link to character sheets using Avrae.

Game consoles are a nightmare from an interface perspective. The controller is very limiting. Since there's likely to be a need for a lot of text input, it gets awkward fast.

They're already doing it for phones and tablets, which may be enough for your needs.

Also, your potatoes may well be easily sufficient. A VTT just isn't resource-demanding in the way a real-time game is.

If the VTT will run on our phones then that'd be great as well.

The thing with phones is if you're needing to see battlemaps and tokens then most phones aren't going to display it very well. It's possible, it'll just be annoying. That's never going to ever change because it's caused by the screen size - which will always be small for phones. Now, tablets are a bit better and running on a tablet is a lot easier - just open the browser and use Roll20/AboveVTT/etc - they'll work spiffily.

If all you need is to share rolls - you don't need a VTT. Discord works on phones with a dice bot that can let you roll from the sheet - you can even bring your character in the D&D Beyond app, click to roll something on the sheet and Avrae automatically relays it into the discord for you. And, being discord, you can still be on call/voice together without worrying about the call time. 

And I keep mentioning Roll20 because when I first used it I had a very old laptop that barely ran anything - not even minecraft, it was worse than any modern "netbook", because it was a very old, refurbished, second-hand thing I got for £40. And my internet? Barely beyond dialup. It was phone data - unlimited package that I used as a hotspot, it was barely (and I mean barely) faster than old dialup. 

And Roll20 ran on that thing, with that shittiest of internet, flawlessly. 

Literally any computer, smartphone, netbook, whatever made in the last 10 years can run it 100% perfect. The VTT isn't perfect, but it will run fine. And over the years I've run it on everything I could, from iphone, ipad, netbooks (2 were chromebooks), 3 types of laptop (Dell, Acer, HP), android phones (mostly samsung), PC (windows 95, XP, Vista, 7, 10 and 11) as well as Linux (Ubuntu). From shitty barely above dialup internet, to full modern fibre-optic broadband. And it worked from "well enough" to "flawless" on everything.

Oh, and I even got it working on an Xbox 360. Awkward, but worked.

There's no downloads and the most minimum of graphical requirements - anything with a browser can run it, including consoles if you're deadset on that for some weird reason.

But yeah, your potatoes will be more than capable and it would be easy.

I am not sure a console VTT would need a lot of text input. It is not trying to replicate a single player rpg. The DM is still expected to tell the story vocally. A controller is good enough to enter names as labels for your minis. A controller is fine at drawing a map or moving minis around. Controller can roll dice. DM is going to need to use a PC do things like upload maps and handouts.

VTT on consoles will likly be a bigger issue than pushing it onto phones or tablets. This isn't from a performance or even controller perspective, but all of the major consoles have some very specific limits on the type of scripting and content that can be added in as DLC/mod/extra content. (Some consoles platforms have tighter restrictions than others - looking at you Sony)

While that in itself is surmountable (e.g. lots of games sell DLC via these platforms), it would strongly hamper the model for the VTT - at least if there is ever going to be any scope of adding any kind of homebrew content or graphics (even if it was through a controlled mechanics like dndbeyond). I know that homebrew probably isn't the first on the list of the priorities, but I think WotC would be smart enough to recognise that enabling a community to interact with your tools for increased uptake (Well that - or it's all going to be across all platforms with microtransaction hell for purchasing every individual chest, chair, steps, and goblin asset you want to place)
