Well, this is the first chance I've had today to post and I'm just tied up in general, but thought I'd post some thoughts.
At first I was disappointed with the 2 SKU situation, but at the same time I understand where Sony can see the justification for these prices. If we were to remove the names Sony and Microsoft from these machines, we'd almost see a progression of four consoles within the same line, at $100 increments with improvements at each stage.
$300 buys a console
$400 buys a console with 20GB HDD
$500 buys a console with 20GB HDD + Blu-ray
$600 buys a console with 60GB HDD + Blu-ray + I/O Features and WiFi
In this context I see Sony's pricing as wholly justified, but the 'sweet spot' pricing of the MS consoles has to be acknowledged. How $300 and $400 have become sweet spots tells you something of our present trends.
I'll get myself a $600 PS3 at launch - just because - but I mean, I can see it becoming a psychological wall at some point after launch. We'll see when the first price drop comes and for how long the consoles will continue selling out upon hitting shelves.
I wonder what sort of effects all of this will have on games; will key exclusives be able to move PS3's among the poorer teen/college set? Will reverse-engineering that logic cause developers to more strongly consider 360?
I don't know, I may have posted some stuff that others have already mentioned... and sorry if I did, but I don't have the luxury of reading through at the moment unfortunately.
