PS4
Upgrading the hard drive is pretty easy and does not invalidate the warranty - check out somewhere like this for a quick guide. 
The PS4 uses 2.5" hard drives and the height has to be 9.5mm or less so the options are not quite as open as you might think - you can find 2TB drives now but they have only recently become more available. TBH I think 500GB is probably enough for most people - in general you are only playing a few games at a time and the time from inserting a disc (with nothing installed) to getting to a playable game seems to be pretty low in the games I have played so far so uninstalling games you rarely play seems to be workable.
Kinda surprised that with the price sensitive nature of consoles that neither of them have gone for 3.5" hard drives instead given the potential cost savings - it would affect the form factor of the PS4 but I would have thought they could have found enough room in the XB1 for it! I guess there may be other factors that favour the 2.5" drives though - thinking primarily of heat generation/power consumption.
I have one BTW (with Killzone and BF4 at the moment) - very happy with it in general although definitely hope they improve some aspects of the firmware in the near future. Also think the store and music unlimited app could use with a good sprinkling of fairy dust to make them more usable.
Only other slight grumble is with the battery life on the controllers - the charge on the DS3 seemed to last forever but for the DS4 I seem to have to plug em in far too regularly for my liking!

I am official bored with my PS4 now. 
I have finished Blackflag.. Battlefield 4 is full of serious 'must kill you' types that take the fun out the game.
Fifa... is ok. Need For Speed is so borrrrrrrrring.... Killzone is pants!
