Fifa 12 Players?

I have FIfa 12 on PSP but there are 2 players from the Arsenal squad Alex Oxlade-Chamberlain and Ryo Miachi that arent included however ive been told they are included in the xbox version.Can anyone confirm this at all please if they have that format or if you have it on psp or maybe even on the DS are they in there version?many thanks

They are in the most recent PS3 roster update, so it is safe to assume that it is also in the XBox
