Because they haven't finalized box design yet? I/O features like number of USB ports, card readers, wired and wireless connectivity options...
When you think of it... They were also vague about insides as well. x86 architecture, multi-core, AMD APU... but no actual specs. Graphics are expected to be somewhere between ATI 7850 and 7870, and CPU can be both 4-core and 8-core, with unknown clock speed.
Sony might be doing this intentionally, not wanting gamers to focus on hardware specs, but on content.
But also... Sony might leave themselves enough space, 6 months down the path, to put inside better hardware without breaking compatibility, which is one of beauties in using standard x86 architecture. Current prototypes may be running on, say, 4-core A10 APU, but as long as there is pin-compatibility, final product might end up with (fictional) A20 APU with 8 cores and improved graphics.
I think Sony played this fine, if I am correct. They gave us idea of what PS4 is going to be hardware wise, but haven't already locked themselves solid in configuration that MS can proclaim inferior is a few months, when X720 is announced.
