Sucker Punch Set To Announce Something Today

inFAMOUS / Sly Cooper developer has been keeping a secret - for two years, at that. What could it be?

If you go to their facebook page, you'll see post that teases a big announcement:

"Today is very exciting day. We've been holding a big secret for the last two years and at GDC later today... We get to tell you all about it :)"

With inFAMOUS 2 already announced and coming in June (which we couldn't be more excited about), you'd be forgiven for thinking it might be the long overdue Sly 4, itself hinted at in the original inFAMOUS and in a video unlocked when you complete the recent Sly Collection. Such hopes, however, were dashed, with Sucker Punch adding:

"Ok everyone No a sly 4 announcement is not the secret. Sorry to disappoint some."

So what, then, could it be? Something new? inFAMOUS for NGP? Sly Collection for NGP? An inFAMOUS vs. Sly fighting game? Multiplayer for inFAMOUS 2? Speculate away!
