I know that QQ has polls, I've been here since the inception of the site. The thing is, QuadraphonicQuad (as great as it is) isn't the center of the universe: there are hundreds or thousands of purchasers of AF product that don't know about or don't come to QQ. AF putting a poll up on their website or facebook page is more about engaging their fanbase and giving them a voice and getting them excited about what exists in quad than it is gathering actual valuable market research. Not everyone has the same level of arcane knowledge that we do here, and every person who's eyes you open about what exists in the vaults of the major labels becomes a potential purchaser which adds to your leverage as a licensee. It doesn't serve any positive purpose as a business to take consumer interest for granted - you should stoke it at every available opportunity. It's a much better position to be in where you have people rabidly asking for things and you as the business saying 'we're doing the best we can' than not asking at all.
As far as what's available and what isn't, it's nice that you've decided to annoint yourself as Marshall Blonstein's mouthpiece, but there are exceptions to the rule, even within AF's own quad reissue program - they put out Blood Sweat & Tears II, which had already been released on SACD not once, but twice previously, and the Jeff Beck Group SACD they released came out as a remastered CD via Iconoclassic Records literally a month before AF's SACD came out. In the words of Captain Picard from Star Trek, 'things are only impossible until they aren't' - these things are a fluid situation and for every month this program is in existence, old licensing contracts expire, label relationships with artists change, etc. At the very least, there seems to be no visible barrier to at least two of the other Earth Wind & Fire quad mixes being released other than the location and quality of the tapes.
