I'm a PC-gamer myself and personally I think it's a bit insulting. Not just towards ps3 players but also towards the PC-gamers.
In case a lot of people have forgotten, The Elder Scrolls started on the PC. Just like Fallout did. That's where it's got it's first loyal fans and I think they are forgetting that. It's like they are a husband that says "sorry but that girl is offering me a bit more in bed. I know that you have been very loyal and giving ever since the start and have basically helped to shape me to what I am today but she's got a better offer for me right now so....bye!"
It's like PC-gamers are getting screwed more and more and it's starting to really really annoy me. Yes I'm aware that the consoles bring the most money but come on! Have some loyalty to the hardcoe fans that you started with too.
On another note I also think it's extremely unfair towards the PS3-users. Us PC-gamers have at least mods but they don't. It's a little unfair to first say that you release on PC and consoles and then later on say...oh but you get a little bit extra and the rest doesn't. That's just unfair and insulting. If you release a game then either do it exclusively or don't but don't try to do it both ways.
It's like saying to a kid "oh sweeties I love you all equally." Just to lean down next to one of them and whisper. "But you are my favourite." It's just insulting towards the others because they are just as good as that one.
