Ed Boon says Mortal Kombat vs. Street Fighter is inevitable
Thanks, but no thanks..

Street Fighter X Tekken v2013 receiving positive reception, top players debating if Paul is top tier
This is actually one of the times people saying "I've been playing that character since the beginning" actually seemed true. There were quite a bit Paul players during the time i played. So before the rest of the FGC finds out she's godlike, I've been playing Nina since like week 2. haha.

Boon: Mortal Kombat 9 sold closer to 4 million units than 3 - likely outperformed vanilla Street Fighter 4
You also have to take into account that Street Fighter also has an actual arcade version.
