Studio XPS 435MT & 435T Overclocking potential - BIOS upgrade?

Judging by Dell's current take on the overclocking subject, I imagine that it's true that the new i7 Studio XPS system cannot be overclocked even though other manufacturers using the 920 i7 solution report great results overclocking the i7.  Indeed, even CNET reviews such a system making the comparison between the Studio XPS pretty stark, given the similar specs elsewhere.  I believe they overclocked the Velocity Micro i7 920 system to 3.0GHz with no issues reported.

Is there a chance that Dell will be offering a BIOS upgrade that will allow the ability to safely overclock?  Or BIOS update to allow for 1333Mhz RAM to work as stated in the 435MT manual?

On a second issue, I've seen reports that the X58 chipset/board actually will allow for a maximum RAM of near 24GB, double the Dell's reported maximum of 12.  Will the Dell eventually allow for 24GB?  On the other hand, I've seen max 12 reports, too.  Just wondering where it will really fall for the ultimate upgrade.  EDIT:  Appears the 435T board will allow for 24GB (MT stands for Mini Tower and T stands for Tower).

Thanks for any insight here.
