I think I can echo what most people said which is to mix up the hardware if possible, if only to negate the effect of people who found hw for last year being able to just dust it off and run a new bench.
That said, I also wouldn't mind a 6x GCN1 stage as well, my 8970 is chomping at the bit ?
Also as always I'd like to see an igp round, although pre-ddr4 and maybe pre-ddr3/no fm2/+ so that it's not a straight rehash of TC.
Only other thing I'd like to see personally is no titans, no 2011+ xeons, and no rtx 2000 series to keep the potential buy in price for stages from ballooning too much.
