The only reason I say
No.
Is because the current HDD that the 360 uses wouldn't fit on something with that difference in size. If they were to make a slim 360, it would have to be able to fit the current HDD size.
+1 for Sony using non-proprietary HDD's.
That's probably like the Microsoft Upper-Echelon of Employees Blu-Ray Add-On that we'll never get. Hah..ok maybe not. Would be funny tho.
