Hmmm, that's true. The only reason that I don't want the 5th gen games on a new handheld is, because I just bought my DSi(and I'm very happy with it), and I think my parents would 'freak out' if I alredy buy a new(like they cal it)"gameboy".
Maybe they can make the first 2 games for a regular DS and then the third of the serie on the new handheld.(But i'm sure that won't happen.)
