Whilst I don't think it is necessarily a bad sign, I also don't think it is a very good sign. So far Titanfall has been hyped beyond any reasonable expectation, so much so that the hype must be reaching the average Joe gamer. I believe the reviews will be mostly positive, but they will also firmly plant people's feet on the ground regarding the game. It is a new IP, it is cross-generation, it is online-only, and it is published by EA. This means that it will not be as good as it could be as that usually comes with fan feedback and the second iteration, it will not be very pretty (which could perhaps the only valid reason to get it on the Xbox One rather than the Xbox 360), it has a limited audience, and there will be issues with the servers.
In short, Titanfall will review very well, but it will only review as well as it can do being what it is, and that score will be far lower than those who are hyping the game believe it will be.
