What do you want in the next Metal Slug game?

All great idea's fellas, i like the shock troopers esque different for each character idea. I also would like the next MS to have a whole lot more different choices in paths, more hidden bosses, (Streets of Rage 3 owned in this area, i think snkp could take some pointers from konami to make the replay value higher) different character related endings and story (maybe like SS5) to make the game deeper/more memorable. Finally be around as lengthly as MS3, a standard was made with that game & i think snkp should strive to keep with it.
