Are Sucker Punch Thinking Sly Cooper 4?

The demo, which is one of the longer demos in recent years, allows players to get a feel for the games mechanics and mission types. There's also the hint of Sly Cooper 4 hidden for avid players.

Those of you that have the demo can locate the Cineperplexed Movie House which is showing none other than - you guessed it - Sly Cooper 4.

With inFamous having gone gold last month we can't help but wonder if plans are already starting for Sucker Punch's next PS3 game.
