Also, any ideas on how much the season pass is likely to cost?
The season pass will be $50 so if you know you're going to but the DLC anyways, it's worth it for the few extras included.
Don't why would you? You should get the xbox 360 HE for a numerous amount of reasons. First it's 25 quid cheaper. Also, considering you would get the season pass on 360 and xbox one, as it transfers over to xbox one (they explained this in the FAQ, I could link it to you if you want me to). Furthermore, It has everything from the HE of xbox one on the xbox 360, There's no difference apart from the fact that it has the xbox one game or xbox 360 game. Finally you can upgrade from 360 to xbox one for 10 pounds, so you would have the xbox 360 and xbox one version of the game all for 79 quid. So, why would you want to get something that costs more? But gives you less? e.g Getting 360 HE gives you the season pass for 360 and xbone, gives you the game for xbox one and 360, all while being cheaper.
i only paid £85 for my h/e ghosts in xbox one so i wouldn't get any saving if i paid £75 for the 360 version. but i agree with raza it is a wise perchance to get the 360 version and pay the extra £10 if you are being charged £95. look around and compare prices you will alway save money if you take 10 mins to check.
I actually ended up pre-ordering the xbox one hardened edition for £74.99 from Gamestop UK which has now sold out.
I wanted to get it from GAME as their hardened edition has exclusive extra's apparently, but just not worth £95 to me.
