Well, I was there yesterday, it was as much fun as I remembered, if not more. This year it appeared that the balance was towards wine dealers over independent growers, but that might just be my impression.
My personal find was
Tour de Belfort, a small organic french grower with a UK presence (in Macclesfield! no they don't grow there). Their wines are classic french style with a degree of freshness, no sulfites. Quite limited range of white (1) and red (3). The reds are all effectively the same blend of Malbec & Cabernet Franc grown nearby Cahors. I bought a case of their red @ £10.50/bottle, which I think is probably worth nearly double. I'll be keeping it for a couple of years, when it should be amazing.
Apart from that there are a couple of other items of note which I can pass on.
Waitrose own label wines in general, and the Grenache in particular (
http://www.waitrose.com/shop/ProductView-10317-10001-224052-Waitrose+Southern+French+Grenache ) - These are curious items, the Grenache is the entire output of a small vinyard, one of only four in the Appelation using the particular grape (a little known used-to-be-popular variant of the grenache) and unlikely to be sufficient production to last a year, at £7.99 again you will have a wine worth about 2x that.
Next, Lidl. Yes, Lidl. They were there and I had a fascinating chat with the chief wine buyer, they are being serious about trying to play with the serious boys - almost all the wines I tried were astonishing value... here is the page of the reds
http://www.lidl.co.uk/cps/rde/xchg/lidl_uk/hs.xsl/34859.htm - the Rioja is particularly noteable, and the claret at £4.99 punches well above its weight. On the white front
http://www.lidl.co.uk/cps/rde/xchg/lidl_uk/hs.xsl/34858.htm the Chablis at £7.69 would be my choice, and not forgetting the Prosecco @ £6.99
http://www.lidl.co.uk/cps/rde/xchg/lidl_uk/hs.xsl/34860.htm And the best thing, according to their wine man? It doesn't say Lidl anywhere on the bottle.
The overall verdict? So many wines, so little time .....
