This is Charles Brown's "Locus Preliminary Recommended Reading List 2008".
Note that a number of them haven't even been published yet, and are apparently known only to those who have read the ARCs. (This list was OCRed from the list distributed a the panel, and although I proofread it lightly, it almost certainly contains errors. My OCR program wanted to read 'Gollancz' as 'Gollum'. Really.)

Comments by the panel:
Gary K. Wolfe (when asked to name his five favorite novels): Neal Stephenson's Anathem IS five novels.
Charles Brown loved Memoirs of a Master Forger.
Several panelists recommended Ursula LeGuin's Lavinia.
Graham Sleight said that Cory Doctorow's Little Brother was a 'strong contender' for one of the five best.
Sleight liked Richard Morgan's The Steel Remains (not listed above). He thought it explored the nature of masculinity.
Sleight thought that Tom Disch's forthcoming novel, The Word of God was notable.
Wolfe liked Margo Lanagan's Tender Morsels.
1. Heinlein-type novels. American pioneers in spaaaaace.
2. Merging of SF and fantasy.
3. Lots of concerns that too many sf in-jokes and easter eggs will put off new readers who aren't familiar with the genre. [Yes, we've heard this concern before. Why don't we just stop doing it? Maybe the problem is that editors don't edit any more, which is another trend we've heard before.]
4. You can no longer distinguish YA from the rest of sff, and you need to read it if you want to understand what is going on in contemporary sff. This is due in part to Viking editor sdn going after Big Name Authors and getting them to write YA.
