Now, personally I'm not 100% still in thinking this will happen, but it's a manner now that we can reconcile the dramatic price-drop with some real manufacturing-side drivers.
On the other hand (see, here comes the positve spin, the optimism that never manifested itself... so far ).
Rumble is ready, there is plenty of AAA games ready for XMAS to back up the machine, the price reduction on every crucial component should be done, the warehouses are totally filled up, PSN has content, Eye Play is done, home is nearly there with a open beta, LPB is on schedule for a beta(?), the PS3 is percieved as being a 500-600 dollar console which makes a 2-300 reduction a total steal. And the dirty secret, Blu-Ray needs a 299,- player, If Sony wants to drop the Megaton Nuclear Dirty No Enemies left Bomb in the console war and REALLY make an impact this is it, and november would a perfect time for the most perfect move yet to be seen in any console war.
No more pussy footing around making semi sick pr releases about percieved success and being the fat kid on the block that once could. 399,- would be a "nice" effort just not a big "in ur face" effort, 299,- is a nuclear wake up call, the games has begun, the king is back and he want the queen to return to his chambers...
