Well, if it follows in the footsteps of Skyrim and Gears of War 3 CEs just keep an eye in GAME where it will turn up at full price (

) . . .closely followed by a 20 quid reduction . . .eventually followed by a decent drop in price - normally around half.
Is it even worth 60-70 quid

. . .dunno, I'll just play it by ear. Guarantee it'll be dropped by Christmas
