Yep, I'm sure it will be Scheduled for Xmas time, then get delayed till 2015.... Till we have an actual release date, it does not count. Don't get your hopes up...
Till we have a release date, it's just rumor, they will TRY to get it out in 2014... Just remember Titanfall and Watch Dogs were release titles for the Xbox one.... Think about that and you'll know what I mean...
Not exactly the same though. Launch titles have very limited time with the actual console and it's SDKs and whatnot. Obviously it's possible that it gets delayed, but I don't see any reason to baseline expect it to get delayed.
