Umm, no there won't be two ELITES; the sections for Black Ops 2 will simply be upgraded to "2.0", with MW3 sections staying as they are.
You can tell this is what will happen because they have TABS for Black Ops 1, next to MW3 on the menu, Black Ops 2 will simply be added to those tabs, which you will click, then choose your section for Black Ops 2.
People are still buying ELITE just now, if those subscriptions weren't transferable there would be an uproar, and ATVI would HAVE to say that you wouldn't get access to Black Ops 2 features, otheriwse it would be misselling.
Kind of how Elite for MW3 really doesn't do anything for Blops, Elite 2.0 won't do anything for MW3.
What I don't understand is why anyone would really care, you aren't actually considering buying that junk again are you? Just stick with the free version and don't give these people anymore of your $$, it just sends the wrong signal.
DLC - There was 28 pieces of DLC for MW3
Collection 1 - 4 MP maps, + 2 Spec Ops
Collection 2 - 3 MP maps, + 2 Spec Ops + 2 Face Off maps
Collection 3 - 4 spec ops missions + 3 face off maps + chaos mode
Collection 4 - 5 MP maps
+ 3 free maps
cost for all collections was 45.00 dollars
cost for elite 50.00 dollars
if you want to look at it the other way, you actually dont save money, it costs you 5 more dollars to get elite vs buying all dlc seperately
i dont do spec ops, and i dont do zombies, so those dlc content isnt for me, but meh, it is what it is... i like elite, so i will buy it again.. some wont..
you can get elite 2.0 where ever Black Ops 2 is sold.. but there is no info on what is included, if DLC is not included i dont think its a buy for me, if it is included again, its a no brainer..
