And obfuscation from Spencer it is very obvious that it is timed exclusive. If it wasn't he would already have said it is exclusive forever, just as they and EA did for Titanfall. Trying to muddy the waters by implying they have helped with development proves nothing.
It is timed exclusive, nothing more or less and MS are trying to imply that they have tied up the full exclusive but can't say that as it isn't true. That is the dishonesty people don't like, trying nod and wink to gamers that, yeah this is a full exclusive, while not actually saying it outright with phrases like "coming holiday 2015, exclusive to Xbox". So when it does eventually come out on PS4/PC those few people who buy XB1 to play the game have nothing to complain about because every statement makes a mention of 2015, even though they have all be worded in such a way to imply that it is indefinite and 2015 is just the launch.
Anyone still arguing that it isn't timed exclusive, if it wasn't why hasn't Spencer/Harrison/Major Nelson come out and used the word "forever" or "indefinitely"? That would clear up any and all confusion right away. The omission of such language is proof enough that it is timed exclusive, and the concerted effort to confuse people is yet more proof.
Why even bother getting involved in this shit show? Let MS tie themselves up in knots trying to pretend and imply that it is fully exclusive and just count down the days until the deal is over.
If that was the case then why didn't Spencer end all of the confusion and just say "It is Xbox exclusive forever" instead of using bullshit language like they have? We have an example with Titanfall where once the deal was made for the lifetime exclusive articles and quotes popped up with that information using words like "forever", "lifetime" and "indefinitely". The lack of this language for RoTR is very telling.
