How long do you think it'll be til FSX is gone?

Unfortuately XP10 development seems to be going at a snail's pace, which means the much needed improvements necessary to win over the market will be too little, too late, once P3D v2 appears. Not saying the latter will be better, but it is a natural successor to FSX/P3Dv1 so LR will have to get their finger out (more resources etc)!
