they have them in small quantities, what you are looking for is Actiontec MI424WR Rev G
You can't request one yet, so I would wait a few months or closer to the end of the year, before you see these in large quantities.
a guy at dslreports got one on his repair. so from what I hear it's whatever is in the wherehouse is what you get. they don't have a way of specifying what rev router a customer wants.
