I think that's not necessarily true. At least not for a few people. I'm a big fan of Medal of Honor: Allied Assault and Call of Duty 1, and I think that the direction those franchises took after the original developers left went nowhere but downhill.
So when I read that a good chunk of the people who worked on each of those games originally (including Vince Zampella) went on to form a new studio to work on a new project, I was very excited to see what they could do. Something new, something innovative - but that was only wishful thinking. I'm more or less indifferent or maybe even against TitanFall now simply because it looks like a glorified later-day Call of Duty reskin after seeing some Alpha gameplay videos.
What are the arguments that it isn't a glorified Call of Duty reskin? That it has mechs? That it has jetpacks and wall running? Those thinly added layers of gameplay additions to the gunplay that resembles the later Call of Duty games were hardly innovative or "risky" to have done. This game was a safe bet from the start of development, and I would go so far to say that some people can easily mistake it as a new game in the Call of Duty franchise.
But, for the people who are big fans of the later Call of Duty games, I think this is going to be a definite buy for them. And I think that was the point from the beginning.
