Well if you want to play roulette with Linksys you can give that a shot. From what they told me those were the very first V2's to come (last week) in so maybe a couple weeks before you see them trickling out to retailers.
Luckily you guys know there is a V2. I found out after I purchased based on WRT1900AC product page. Doesn't even mention new specs. The amount of trouble I went through to have LinkSys replace V1 with V2 has been pathetic. WRT1900 better be worth it. Not sure LinkSys (Belkin) is.
