I just bought an A3 and have been enjoying it. I really would like HDDVD to win just because Sony values short-term profit over all else, and their rootkit debacle a while back really pissed me off. I have a PSP I'm pretty happy with (albeit it'd still be better without the retarded UMD disc format), but aside from that I really try to avoid Sony products, and hence went HD-DVD. Now, I also don't have much love for Microsoft, so that wasn't so easy either
That said, I am really sad to hear about Warner's and do think the best bet now for Tosh is to 'go for broke'. Win back some studios (convince MS to kick in some crazy incentives somehow), and sell players at a loss. If there were lots of $99 players available (basically, A3 quality), and a (I hate to say it) pirate-friendly SATA-interfaced writer, I think we'd see a lot of momentum. Don't forget that Apple really isn't a big fan of Sony, even though they've been buying components from them since the original mac (but less and less over time, I think maybe almost nothing at this point). Sony hates Apple for the iPod's success, and Jobs seems to have reciprocating feelings in general. The fly in the ointment there is really that Jobs likes DRM or at least slowing down pirates, due to Pixar and Disney relationships
To me one of the most interesting facets of this will be if the porn industry actually plays a role here. I know Sony doesn't want porn on BR, and so those content producers have been exlusively HD DVD. Now, I don't know why exactly most people would /want/ porn in HD, it's bad enough I have to see every wrinkle on David Letterman's face on CBS, but if that takes off, HDDVD would seem to have a fighting chance, as adult content has driven so many technical innovations and helped end format wars before. (I am actually not much for porn DVD in general personally, although I don't think there's anything wrong with it, and I think it's a fascinating if overall vaguely negative industry.)
Ultimately, Microsoft (and likely the porn guys too) probably believe the future is in downloads and doesn't care hugely about the optical disk formats, at least not enough to throw hundreds of millions of $ at it, unless they thought they'd recoup it in licensing their scripting engine. I doubt that's the case (if we're ever to see lots of $99 players anyhow), and at this point they have mostly given up on trying to fight Java, so that's not looking as doable
Overall, I'll be really sad if I have to start giving Sony my money via disc licensing or for a player. I'd much rather support the somewhat-less-evil Toshiba and Microsoft (shudder), and their simpler, more open disc approach. (And I can't wait until 2 years from now when "disc rot" strikes all these BD discs with their super thin coating... I really expect it to happen out in the "real world" of imperfect conditions.)
Ah well. I probably won't be buying as many HD DVD discs as I had hoped to at this point (partly because Warners owns a bunch of my favorite films), but I will continue to support it because I think long term, it's better for consumers as a format, which is why VHS won, in my opinion.
