There will supposedly be sold with the choice of either, 250GB, 500GB or just 16GB.
Obviously a 16GB model would cut down the price drastically. Similar to the 4GB Xbox 360 model.
As you can see, there doesn't seem to be any exterior difference in the different HDD sized models.

There is still rumors of it being a 'flip-top' loading system, which you can barely see an possible divide line in the last picture,
but these pics were taken for the purpose of legal classification apparently, hence the unphotogenic angles and quality.

So what do you guys think of the design, which is clearly returning to the PHAT design, just shrunk overall?
