Damn that sucks for the developers. Microsoft better pay quick, there's no excuse. Also why does Microsoft even pay only once a quarter? That's fucking shitty for indie devs! Just imagine being an indie developer and not having your money you made on Xbox from July 2014 and later...
Edit: via Neogaf, 3 more people who claim to be developers who haven't been paid their Q3 payment yet. Even one of them is considering not releasing future titles on Xbox, so it could also bite Microsoft in the ass.
OnPoint: ''Yeah, they haven't paid us either. This is becoming a real issue. Makes us question ever returning to a Microsoft release again, I can tell you that. Source
Robert at Zeboyd Games: ''We haven't gotten paid either. Unfortunately, this is nothing new for Microsoft - it feel like half the time they're late with XBLIG payments.'' Source
DSix: ''This is true, I have yet to get paid. I mailed their services, and they assured me "it would be solved in the coming weeks", but I need that money now, not in months when they finally figured how to input my fucking account numbers in their system.'' Source
