The issue for a lot of people not thrilled about the newest PDF, I think, is that it's not a new game; it's a revision of a game we've been playing. I wanted a new, different game and this PDF looks a lot like a cleaner version of a game I already have.
Nobody's right - it's down to preference - and the gloating over whose side won is pointless. But don't expect people not to voice their disappointment with this decision.
I realize that, but to many of us, the iterative, evolutionary approach is nothing new, because we're used to it ever since Dark Heresy 1st Ed. Some even longer than that (what with WHFRP). To us, change for the sake of change - i.e. "wanting something new" - doesn't hold any intrinsic appeal.
Like you say, much of this just comes down to preference. The last thing I want to do is to start over on a new system and start polishing it from scratch again.
