Games?
I dunno, they've pretty much sucked the current manner of gameplay dry with RBY, GSC, FrLg, RSE and even DP, so I don't think that they'll be making any more games of that genre.
But still, you have platforms, strategy games, different manner of RPGs [i.e. different engine]. If they alter the gameplay in future games they can make them interesting to new players as well as the old ones. I just can't imagine them giving up on something that makes them that much money [I'm reluctant to use the word 'earn' :-/ ]
I mean, even though Mystery Dungeon games left a lot to be desired, it was still a nice refreshment. Give it some time and future versions of it may have what the former ones lacked, such as greater replayability, for example.
Who knows what the future brings, I still wouldn't mind a nice, big, spectacular PC Pokemon RPG with multiplayer options to blow your minds. You think Nintendo isn't out there right now plotting a Pokemon MMORPG? Think again.
But, I guess we'll have to wait and see
