Title says it all, and I'm talking about retail AA/AAA games. Sure we've seen some new IPs like SO, Scalebound, Quantum Break, etc. But these aren't made by MS themselves. So the question is, when do you think MS will reveal a new IP that they are actually making? I'm a little disappointed it's taking this long to see a new IP from them, they boasted about the "8 new IPS" at launch but they ended up being by third party or smaller titles (I don't even know what the 8 new ips were tbh).
We know Lionhead has been working on a new IP, Rare could be making one as well.
Personally I think we'll see a new IP from either Lionhead or Rare at E3! Finally MS!
