I think getting snarky with Hasbro in the Q&A isn't going to get you cut off... I don't know of any site that asked pretty beligerent questions to Hasbro that got a pink slip from the Q&A, not off the top of my head anyway, but sites did get non-answers back or short replies that didn't ultimately address what they asked.
They're still getting free stuff to promote, they're still part of the Q&A...
Jeff put it best. You can bitch at Hasbro about anything you want, but what you get in reply can either be taken for what it is, or you can assume you're getting a non-answer to what you asked, or whatever. We ask what we think we'll get responses on, generally. I could bitch to them about playsets, to-scale vehicles, more articulation, lower prices, better distribution, etc., and like Jeff said, you can pretty much write the answer to your own question you just asked and you've gotten nowhere and gained nothing.
It is what it is. I too won't be shocked if there's no Q&A time at the end of this session either. They don't really want to hear it and they're not going to say, "Yes, you're all right, we are screw-ups and should let collectors run the line", which is unfortunately what I think a lot of people are looking for at this point. No fingers pointed anywhere here with that, but I think it's sometimes the truth.
I've been privy to some info recently that puts a lot of the line's items and decisions into perspective... It answers a lot of the, "Why don't they just make _____" type of questions, from an insider's perspective, and it's not a simple black and white issue unfortunately, on most any subject that's being brought up these days (from specific toys getting the shaft to distribution). The Q&A's aren't where the answers will come from, as to the things that really anger the collecting community, ultimately. Most of the sites are pretty frustrated too, and even coordinated the Q&A's to get the most of out the sessions, and it still didn't produce much in terms of the results that collectors were wanting to see in the answers given back.
I think the line at large is in a state of flux too. I think that's going to hurt the Q&A till it's back to stable. Just some speculation there, but I think it's possibly true.
