In my efforts to stay awake, I ran across this on ebay. I donno if it's old news or whatever. The description said the card was from E3.. (the actual preview of this had an GBA-SP and book from E3 in it also, I just cropped it to save on loading time, if you want me to post the entire picture, I will) and that it was for Pokemon Ruby and Sapphire.. it didn't mention anything about the e-reader.. so this is all just speculation.
