Yeah it was kinda far-fetched, but I know the reverse will happen, people'll be spriting 6th Gen Pokemon. That's why Serebii's section is planning that project as early as possible - Either whenever all Pokemon, with names, are leaked, like with B/W, or at release date. Whichever comes first. I would suggest the Pixel Art mods at PC to do the same, but I hate to start a forum war with people from PC saying Serebii copied them, and vice-versa.
WSC: Weekly Spriting Contest
PC calls it WPC, which I'm assuming is Weekly Pixel Contest. Serebii's is restricted to Pokemon sprite contests where, I'm assuming, PC's is more generalized.
Ah yes, I know Spriter's Resource, of course. It's a shame that it was mostly Nintendo products nowadays that used sprites (correct if if I'm horribly wrong), and now, with the release of the 3DS, they may completely stop, not just for Pokemon. X/Y is where Pokemon Spriting ends, when was last time you've seen a pixelated Mario game? What about their other Franchises? Pokemon was, I'm pretty sure, the only one that stayed behind, until now.
I mean, it's great that they're moving on to 3D games, I'm just dreading the day when spriting, Pokemon spriting, to be more specific, becomes a dying art.
Oh and by the way, for my Mega Mewtwo sprite, I literally meant the shape of the lines on it's head-tail, not the colour XP
