There was a piece on fudzilla saying that a bunch of new hard-drives had been certified and that a new 320GB or 500GB HDD would be available for purchase within the next couple of months.

My theory about the next few months is that they will stick with the 60GB starter pack and phase out the 120GB HDD at retail and increase the HDD size of the Premium SKU to 120-160GB so that they can reduce the price difference between the Premium and Arcade SKUs to say $75 as people will not be able to get an Arcade + HDD with the same space/cost as the Premium and they will offer a 500GB HDD in the Elites and have the HDD size unavailable for purchase for the time being.
Tease.
