It seems like a few of the bigger retailers are OOS on the AX88U. Is this signaling anything beyond just a restocking issue? I'm a happy AC-88U user and my girlfriend needs a new router so I'd like to do the direct upgrade from 88 to 88. Amazon's last price on it was $299 but Newegg has it in-stock for $349. I won't pay that much if I know it'll be back in stock at Amazon. Anyone have any ideas?
