I just got an email from Nintendo mentioning the bundle, or bundles as they put it, that are coming soon. I'm starting to think that there will be two separate game bundles. One for red and the other for blue.
The email states: "Check out the limited-edition New Nintendo 3ds bundles that come with Pokemon Red or Pokemon Blue pre-installed!"
A few key words bundles" and "or" as in we have to choose between the two.
I could be wrong but I wonder why Nintendo would word or this way otherwise. The preorder sites make it seem that you get both games.
I got the same email but I'm going to assume that whoever wrote the email made a mistake, since the box art is clearly both, every other piece of information so far including the stores selling them has indicated one bundle with both games, and if you click on the email link, then click "Check it out" on the bundle, it has almost the same language but:
Check out the limited-edition New Nintendo 3DS bundles that come with Pokémon Red and Pokémon Blue pre-installed!
