There will be various reasons for release dates and sometimes it will vary for very specific reasons (i.e. the 2 week gap between US and UK PS4 release dates). But with Titanfall the gap between the release dates between the US and UK appears to be simply down to the difference in when new games are released for each country. One of my points was simply that if Titanfall was released tomorrow in the UK then this would have greatly reduced people using VPN's to unlock the game.
Obviously it doesn't stop the big variations in regional pricing or currency conversion and therefore people would still be using VPN's to buy the game cheaper.
