Yeah Mark Millar already pretty much confirmed there will be Sentinels.

It's also going to be shot in 3d. Usually I wouldn't be ecstatic with that, but as long as it's shot in 3D and not converted then it should be fine. That and seeing the Sentinels in 3D will be pretty awesome.
Looking forward to this one, just hope Fox doesn't cheap out on some of the effects like they did in First Class.
I still wonder where they intend on going with the future of the franchise though. They have two different, yet successful X-Men franchises they can choose from. Do they keep making movies using both franchises and release an X-Men movie every year, or do they go with just one of them, and maybe have characters make cameo appearances every now and again?
