No because the install base is way too big to ignore. However by next year I think it is perfectly acceptable to stop supporting last gen consoles especially if they release on PC, they already said they couldn't do PC at launch because they QA each platform individually in house. I also imagine by holiday 2015 there will be at least a $50 price drop making next gen consoles more affordable. IT would be smart of bungie and activision however to announce their plans to do so by no later then E3 2015 so it gives people time to save up for it though.
