Titanfall has definitely had an impact and a great start to the first title in the series. It certainly has the basis for becoming even bigger.
The reality is it would have likely been a better game on ps4 and sold more. I think it will be more difficult for Xbox one to get exclusives in future excluding Microsoft's own studios that is of course.
It's possible the next Titanfall may not even be on xbox one. The developer seems pissed that Titanfall changed from being a timed exclusive to a permanent exclusive and has likely meant a loss of revenue for the developer. EA likely pocketed the fee from Microsoft for exclusivity. Also many technical issues trying to get the game running well and has still resulted in a low resolution in the released game on xbox one. So if the Xbox one market share declines compared to ps4 even more I could see Titanfall 2 not appearing on xbox one.
Also very strange about the lack of info, images and video of the 360 version right up to launch time. It's still possible the 360 version could be surprisingly close to xbox one performance.
