And a lost one in Noby Noby Boy.
They are losing a few old ones but they are making new first party Ip, that was the errror sony make in the first 2 gneration they focuse mnore on tird party that they don't make a huge ip like halo or mario is on nintendo and microsoft. Now sony is focusing on ip that you are not going to find enywhere, unlike microsoft focusing in steling 3 party exclusives and dl content. The pay for temporary releasse but then it comes to the ps3 ps3 eclusives they are never going to relese on 360, because sony is the publisher.
