The problem with surround isn't the format, but inability to record great artists economically. Hardly anyone can afford to record a symphony orchestra in two-channel, much less surround.
Most people are happy with processed, synthetic surround, so the demand for high isn't sufficient for the producers to cater to audiophiles.
So I think surround, as an audiophile format, is DOA with no prospects for high rez development.
Meantime, the vinyl meisters have a giant treasure trove of high quality reissue material. The artists and performance quality matter way more than format, next comes resolution and finally format (with resolution maintained, not compromised).
Resolution of vinyl has reached incredible heights. Digital potential is equally good (my 1-bit recordings at 5.6MHz are stunning) but I think that vinyl will prevail, surprisingly, due to ease of operation. After the commercial failure of DVD-A and SACD who wants to commit to a new gamble on 5.6MHz digital? No one, I suspect.
Sorry if Gordon is "bored" with vinyl, but his quest for "spacial" aspects is likely doomed, in my estimation. I hope he's right, but I doubt it.
