The Black and White sequels look good, but I don't think we need Ruby/Sapphire remakes just yet. After all, they're still playable on the DS Lite. As a matter of fact, last year, Pokemon Emerald was still selling in Japan, and pretty well, too.
Sequels are a good idea, instead of getting an "enhanced remake" of every game.
What I do think we need is a Pokemon "Sunshine Yellow" remake of Pokemon Yellow for the DS. Now that would be epic.
I'd love for the first 3DS outing to be a remake of Ruby/Sapphire...if only because I loved the Hoenn region and would love to see it with graphics even better than B2/W2.
I think Absol and Lapras should have a pre-evolution. Could you imagine how cute they would be?
Let's see....in terms of getting better, I would hope Chatot and Corsola would get an Evolution just because they are so darn bad at this point
