I purchased the Bundle a couple months ago, and it included the MToF pre-order. I have two questions, one much more important than the other. 

First, will the MToF pre-order include the introductory adventure that's come out?

Also why doesn't the bundle include other such items (or does it include them and I just suck at navigating the compendium?)?

What other such items are you referring to?

I can't say with a definitive answer, but if the adventure is included with the book then we should have access to it when it is released.

There was an adventure associated with Tomb of Annihilation as well, that wasn't part of ToA. Possibly other adventures, though I'm not sure. Also, IIRC DDB has put out their own OG content a couple times. 

At the moment since there is no Homebrew Compendium content I wouldn't imagine anything not official being given a spot yet. Do you have a link for the adventure that came out with Tomb of Annihilation? I don't remember anything being released with it. The only official one I can think of is the Tortle Package.

The adventure that will come with MToF is an Adventurers' League module.

Ah, and at the moment those are not included on DnDBeyond. So for the time being the adventure would not be on the site? Hopefully with the expected Wizards update to AL that could change?

The adventure will be on the site, starting from tonight. I don't know about the previous AL modules.
