In the thread https://secure.gamesas.com/forums/viewtopic.php?f=42&t=31622, the "Crytek Team" say

"In the mean time don’t forget that a double XP weekend is running right now! so jump in-game and see how high you can rank up!"

Now forgive me for being pedantic here, but it ain't double XP in Europe. Maybe the team spent too long in the "Cafe's" this afternoon.

It's only active on the 360 and pc, ps3's hasnt started yet or have a date as to when it will be.. :/

Holy F*cking Sh!t. They really don't care about us do they. They keep postiing things referring to the Xbox here (well twice anyway) and we always come last on the wish list. Thanks mate

Yup lol. Gotta love it -_-
Anytime

The PS3 platform will also get their double-XP weekend shortly after, when the PS3 patch becomes available.
