Sony will bounce back. They wont take this news without a huge announcement. They surely was aware of this announcement and have something up their sleeve.
Us loyalist are not selling our PS3's over this announcement. FFVXIII is still exclusive.
bring up a good point sony would have to know about it.
1. Square would have come to them asking for $$$ to keep it like Rockstar
2. Square told stock holders about the M$ money deal(if there was one)
...sony owns some Square-enix stock or am i crazy?
so either way sony has already been planning on what to do, but given how things have gone the expected thing is nothing
For Sony to have kept it exclusive this long, there must have been an exclusivity deal in place. Square probably bought out the contract using money furnished by Microsoft (god knows how much). So yeah, Sony must have known about this from the start. It apparently happened pretty recently, though, so whether or not Sony had time to come up with something to counter it tomorrow is another question.
