Yeah, the previous 2.66 was the T9550 so still 35 W, so I'm not too bummed. You're still getting a more efficient processor in terms of operations per Watt.
Wikipedia has switched its assessment. For now, the listing for the 2,80 part is T9600. Presumably Apple will switch to the P processor when it runs out of T9600 stock.
