I don't see why Asus keeps tagging along the garbage killer NIC. Dan's experiences with it are pretty much mirrored everywhere else, it's overall worse then an intel NIC, requires obtrusive junkware to be installed and costs more.
As for the board, if they lost the thunderbolt card you could drop an easy $100-130 off the price tag and people would be much happier. Doesn't really make sense for any but the most hardcore hex core users (well, or L2N benchers).
I've talked to ASUS about that and I think it was Gary Key who said that it's at least being updated frequently now and getting better all the time. Which is true. It's had two or three updates since I started writing the R3BE article up to now.
