Well, that didn't take long, did it? Yesterday Sony said they would make an "electrifying" announcement on Monday. Today, we know what it was.

A photo of an inFamous pre-order box from Best Buy was sent into Kotaku earlier today and a sticker on the front spilled all the dirty details. Pre-ordering a copy of inFamous will get you a voucher for the multiplayer beta of Uncharted 2: Among Thieves. This is pretty big news for two reasons: 1) it's an extra incentive to buy inFamous and 2) multiplayer hadn't been confirmed for Uncharted 2 yet.

Presumably Sony will reveal more details on Uncharted 2's multiplayer when they officially announce the deal. Until Monday, then. inFamous will be released on May 26th so you've still got a few weeks to get those pre-orders in.
