Hardware is not an excuse for not overhauling KOF. It's all about the effort the team wants to put into it. They could redraw and restyle all the graphics in the game, introduce and eliminate a number of characters each year, and redesign the favorites, and the fighting engine. Much like how SamSho evolved from the original, to II, and to III. Each of those games evolved quite well graphically, with very little being carried over.
I feel for what we pay for these cartridges, we're getting severely shortchanged with KOF.
I'll probably download 2k3 before committing any money to it, which is what I should have done with the last few.
