So while I was caught up in Mario Kart, those Japanese magazines were hyping Pokemon without me. Basically there are mega evolutions for Swampert and Sceptile (and Diancie) now too, and there are Pokemon called prehistoric Pokemon, where you devolve them to become their prehistoric selves. This is the case with Groudon and Kyogre. Also, these games will be at E3, so make sure you watch E3!
