possible put the 2 new characters ?

It will happen eventually. I have the feeling they'll do it.

I think new categories is something that is bound to happen, but one problem is that there is already a legacy category for older runs and it wouldn't make sense to merge what used to be current patch into legacy. One way I could see it done is keep legacy like it is and make current Any% pre-DLC/post custom game.

There's a lot to take into consideration. We will wait a few weeks as updates will roll in from the DLC anyways as DOTEMU/Tribute has shown thus far. So keep running the runs and then be ready to turn them in by late September.
