I have a ps3 and am thinking about getting a ps4, but if you get a ps4 I know that you can log into your account and get your trophies and friends ( you can only chat with the ones who use ps3 ) but could you also be able to transfer your gamedata? for example so that you can continue where you left off on watch dogs or call of duty? and also what about your old messages on your ps3? will they show up? please don’t guess but give me a good answer.
