Noel's right. Just because they are working on X3 doesn't mean they don't have a team working on X2b. Dropping X3 in the forum only shows that X3 is in the works--albeit, that could also be re-titled, or re-packaged, released, or simply dropped. There's not as much of a hint as one would infer.
I'm still begging and pleading for X2b, but if X3 has a massive overhaul of Take Lanes, and a way I can remove features of X3 I'm not ready for or don't use, or don't have the horsepower for, I'll gladly take X3 at $99.
I was working in X2a last night, and had no issues. I was quite happy that this is the first session I didn't have a crash (not one in 4 hours!). I was avoiding some things that, in the past have crashed it, but learning how to hack the way I do things has helped, as well as patience with Waves plug-ins. Maybe X3 will make this easier, with higher tolerance of 3rd-party plug-ins, improved performance, and more stability perhaps! (fingers crossed!)
