The MK4 tease makes me either think two things :
1. Reiko is DLC, which is interesting considering hes dead in the current timeline and his past self coming to the future would be interesting
2. It just means they're announcing the DLC in 4 days
Not to be that guy, but I would hate it.
I loved the Marvel Super Heroes and X-Men Children of the Atom games that Capcom did, so any other kind of style would just be whack and unnatural to me.
