I wish more people would had saw that video interview. 

Like Fishy stated, Kaz announced in an interview that Sony would maintain a single SKU from now on. 

I'll probably buy a PS3 when it drops at least at 300$ and FFXIII comes out along with other good games (especially JRPGs which the Wii seems to be lacking so far).

I just don't understand what else they could cut out of the machine to make a 40GB worth $100 less than an 80GB. The smaller HDD is a few dollars difference, at best. Maybe it's the 20gb reincarnated? No card readers, wi-fi, and smaller HDD for a $100 less just like last time?

If that's the case, then essentially all that's happened since launch is Sony threw in a 20GB larger HDD and had a $100 price drop across the board.

Ooh, I know what they could do.

$499 ps3:

80GB HDD
SD card readers, etc.
Wi-fi
Spiderman 3 on Blu-Ray (MSRP around $35, most likely)

$399 ps3:

40GB HDD

Then the $100 difference makes perfect sense.

While they'll most likely stick to their word this time, you have to remember, they said the same thing at E3'05 when MS announced their two SKU strategy for the 360.

The card reader was always the dumbest feature

Sony really needs to hit the lowest price point possible, and now with Ken gone I think the more sensible minds will win out.

Please just drop the price of the 80GB instead. Im getting confused by all these different versions of consoles, I wish all the companies would just stick to a single SKU.

The developers must hate it as well, at least as far as the X360 Core goes.

 From a developing standpoint, all PS3's are identical.  For the 360, however, you are correct.

Considering there are books being written with titles like "Why Did The PS3 Fail?" and Bluray sales are barely above HDDVD sales now, this seems like a good idea, even if Sony loses money.

I would buy a PS3 for $400 if games like Uncharted, Little Big Planet and Killzone 2 get great (90+) reviews.

Well worst case a $599 PS3 SKU is going to be a tough pill for parents and family to bite this holiday season, but a $399 PS3 would do quite well I imagine.
