OK, here's the cold, hard truth (I also really want HOTAS support, for the record):
HOTAS use is still considered very niche. Not enough people use them, and that small group of users is split into different games they play.
A company like EA, and many other behemoths, will simply not put dev time on developing something for such a small group of users. The (dev, qa) cost would simply, in no way, outweigh the benefit (happy, but very small group of players).
So, we can keep adding XP to this topic and letting EA know, at least, that the interest is there; just don't expect any miracles.
