That's as much an EA thing as anything else. EA's post-release support for PC games has been really shitty over the years. I first noticed this when they didn't even bother to make the Mirror's Edge DLC compatible with the Steam release (and they didn't even bother to mention this when the DLC was first released). TOO MUCH WORKDev realities, right Bioware? They don't care about the fans that represent a "minority," be they Japanese 360 players or PC players. It's all about the numbers, and not developer pride at this point.
Then there's the super-keen Burnout Paradise island DLC missing from the otherwise great PC port. Same goes for Dead Space 2's DLC. And how Garrus' face in Mass Effect 1's PC port still uses that ultra-low-resolution texture, ruining every single closeup.
If the projected profit margin isn't quite high enough, EA has no problem ignoring a subset of their fans. They do it all. The. Time.
