I heard a rumour about this a few days ago that this was going to happen, being from (another) 360 fan I took it with a pinch of salt, but today I found this:
(PS3 for R6800, not a bundle)
All the sites that have it listed as R6300 still have stock whereas L&L is out of stock - indicating it may be the price of all incoming units.
Can anyone confirm? Was R6300 just a launch special?
