I quite like the look of the new controller, I might be persuaded to buy the new playstation over the xbox if they can fix some of the issues I had with the PS3 controller. The new shape of the thumsticks is a massive plus in my book, hopefully they wont have massive deadzones like previous controllers. The triggers at the back also look to be an improvement. They're smaller, but the playstation triggers have always been broader than the triggers on the 360 pad, yet the 360 pad triggers are much better(for me at least) as they curve outwards and you can hook your fingers around them, which it looks like I will be able to do with the PS4 triggers.
I guess I will know for certain what I think of it when I hold it in my hands.
