I see that Adorama camera and a few other retailers seem to be getting a trickle of PRS-650s back in stock.
Already showing "this item back ordered from Mfg." again and at Adorama
SonyStyle USA has also had them back in stock off-and-on. (now off again)
They are trickling through though.
I could have bough a 650 at several places in the last week, so if you look around they ARE slowly becoming available.
It looks like those who have them have bumped the price back up to the full $229 retail though
