(adsbygoogle = window.adsbygoogle || []).push({}); I personally think a 128 GB or 256 GB SSD would be better than a 500 GB HDD.
Yeah it's half or a quarter of the space but its much faster and better quality.
I still have my 80 GB fat ps3 that's 5 years old. No one needs 500 GB.
An SSD would make for faster boot ups and faster load/saves. As well as faster installs.

I mean it actually kind of surprises me they aren't doing that

nah..sony wants to improve the "cloud performance" which means alot of data will require an internet download.next-gen console will need more and more space for digital copies.

The HDD on the PS4 is rumoured not to be removable but External HDD's can be added through the USB slots. And yes, a lot of people who don't just play COD need 500GB HDD's.
