Update:  Reason for updating is because of E3 and the fact that we still have plenty of surprises waiting for us from Sony and Microsoft. One thing to note is we have yet to even hear from companies such as LionHead, lift London, Naughty Dog, and Platform next studios.  Check first two posts. What do you think some of the unkown and rumored titles could be? Sorry I do not have Nintendo. If you want to help me with Nintendo 1st parties just send them my way.  

If you know some things I don't I will post them up. No problem.

japan studio from sony are making pupeteer and rain as well. 

Thanks.  Never realized how big of a studio they was lol

well from what i was told they had some trouble this gen, but they reorginized and got their shit together, now they seem to be pumping out games each one more unique than the other. gravity rush, soul sacrifice, puppeteer, rain, knack and now their new game (forget its name). and they all seem amazing. cant wait to see how they perform this gen on the PS4

From this you can gather that much development is done by second-party studios (Yarn Yoshi and Pokemon comes to mind), and we are not 100% sure of who is developing certain games (no clue who is behind Yoshi's Island 3DS, for example).

Microsoft certainly has increased their development profile, haven't they? Do we know if all of those are game studios? I'd bet at least one of them corresponds to Sony's ICE Team or XDev.

Other than Live, one of the biggest criticisms against the Xbox over the years is that it doesn't have that many exclusives, especially if you're not a shooter fan. I wonder if they mean to rectify that? The sports studio is also interesting, anyone know what that's about?

On the Worldwide Studios side, Japan Studio seems to have hit pay-dirt with Playstation C.A.M.P.

SCE Japan is also making Panopticon.

Probably the publishing studios.  I think they are just publishing 3rd party games rather than devloping.  Who knows.  I don't know anything about them other than they are helping 3rd parties.
