With Sony's Gakai stuff not happening anywhere until 2014, and Europe being later than NA, it wouldn't surprise me if game streaming from profiles drops with related issues. I'm curious to see how many promises Sony actually deliver on when day one comes, and how much was vapour - it wouldn't surprise me one iota if we were in an age of pre-baking / target-rendering OS level shit now.
Xbone releasing in the UK a week earlier than PS4 isn't much of an advantage for them here, but it was the right move if they want to do well here. Should be interesting to see the marketing assaults from both of them in a couple of months time.
