IGN may be premiering the gameplay for an unannounced Platinum Games title at E3, but before that, YouTube Live at E3 will have the “exclusive reveal,” according to a new promotional video.

The reveal will be on Monday, June 15.And given YouTube Live at E3 is revealing it first, that means it’s likely not a first-party title for Microsoft or Sony.

Watch the promo video below.

If it's between Sony and Microsoft, I'll guess it'll be Sony exclusive. Unless of course the game is multiplatform.

being revealed by yt and not at sony or microsofts conference, so it will be multiplatform and wont be exclusive to any of the big 3 it looks like

Seems like it. I really doubt a Sony or Microsoft exclusive would get revealed on YouTube's livestream and gameplay shown from IGN. 

It looks like it could be Vanquish 2. http://www.vg247.com/2015/06/11/vanquish-2-e3-2015-platinum-games-reveal/

i remember seeing that earlier, it stood out to me as well. I wouldnt mind Vanquish 2 though

Fully expect it to be a multiplat for one, ps4 and pc. No Wii U.

seems like it will be multiplate. or a self published game that will be timed exclusive to a platform due to limited resources.

I hope it's not another Bayonetta!

DMC5 perhaps??
