Yeah... But as for drm Sony could enable that whenever they want via update.. What you need to remember is it is not Microsoft blocking used games... They have passed the power to the publishers/developers.... So it's them who makes the rules.
Now looking at it like that, developers want control of their games, so who would they prefer to make games for? One where they have the power, or Sony?
You only have to look at exclusives to see who's side developers are on. Ultimate team is xbox exclusive, map packs for bf4 and cod are going to xbox first. The list goes on.

Region free is cool, but most games are released very similar dates and games in the USA don't work out much cheaper so this doesn't really benefit us.
The price difference of the console would take make that much of an impact as there isn't much difference. For example people,especially wouldn't just buy the ps4 because it's cheaper. It's how many a+ games are available and that are coming....

Only time will tell. Both consoles have loyal fans, and it's more down to what my friends get...
