This is unconfirmed, but from looking at the pictures it does not appear to have any opening or area for a user to change the hard drive.  If this is true, how will this affect some of you who were considering upgrading but need more space than 120GB?  What about new users.  Will this affect their decision if they can never upgrade their HDD like is possible on older PS3's and Xbox 360's?

EDIT:  We have found the HDD slot.  The compartment can be seen from the front view.  The latch to release it is on the bottom view picture.    No worries!

I see an opening in the front.... I doubt it's not upgradeable

It looks like it's just in a different location. From the front angle, the bottom right side looks like it's a flap or something that could expose a hard drive.

The hard drive in the slim is still 2.5" form factor.

Doubt it. Its prob a hidden compatrment. The 1st pic looks great

That is the only place I saw where it may be possible.  I'm guessing that is probably it, they just moved a lot of stuff around.  But from the pictures it is unclear that the front piece even comes off or anything.  I showed all the angles and there doesn't seem to be any screws or anything you loosen in order to open that front part....

lol, PS3 Slim tooless construction confirmed!!!111

its still there..plus 120GB is fine anywayz

Imo 120 gig is more than enough.

hmm i think its possible. maybe abit harder , but they don't point it as a removed feature which is great.
