Unfortunately Kris was one of those things, well person in this case, that wasn't added to the remakes that came from the third version (and Leaf didn't make the cut in the originals, if so Red may never had been in GSC). We have seen a lot of examples of things from Emerald missing in these too...
Anyways back on topic, I would like to see some device that Nintendo is thinking of using in the future. That's why I suggested an Amiibo. It'll be similar to the story behind why FRLG got the wireless adapter, which at the time Nintendo was thinking of using for future games (ended up being built in for the DS and beyond too).
