CORRECTED Responding to consumer demand, Sony has restocked the 60GB PlayStation 3 online.
After a complete sell-out of its online supply (first discovered by GamePro earlier this week), Sony has replenished its 60GB PlayStation 3 supply on Sonystyle.com.
60GB PS3s are back in stock online.
When GamePro first reported that the 60GB version of the PS3 became listed as on "back order", Sony's Dave Karraker confirmed that there was no longer any 60GB inventory remaining in SCEA warehouses and that it all had been shipped out to retailers.
Sony has responded to the online demand and now has replenished the online supply of the 60GB version, shipping ample retail supply back to fulfill online orders.
CORRECTION: We errantly attributed statements to Dave Karraker that the $599 80GB PS3 bundle may be reduced down to $499 once the complete supply of the 60GB version dries up. Though widley believed by many, Sony has made no official announcement, either on or off the record to GamePro.
