So far, as of Beta 1, it looks to be kind of a normal Pokemon game. Kid gets Pokemon, goes on journy, stops bad guys. But the design is great, it doesn't seem too big or too crowded, the level progression has been nice, he is incorporating Gen V Pokemon which both makes me want to rip my hair out for spoilers, but also is interesting. XD He also is making use of cutscenes which is very interesting, and is tying things into GS, I think.
Overall, can't wait for it to be done. XD
