If you've been waiting to tie all three of your PlayStation portables to one Sony Entertainment Network account, today's PSN maintenance will make you smile. For everyone else it's five hours of downtime starting at 9AM PT (12PM ET, 5PM UK time) and ending at 2PM PT (5PM ET, midnight UK - that's right, two hours extra for the extra special UK).

There are some other, minor improvements being implemented during the maintenance, but the main one is the bumping up of portable activation slots to three. Once it's done, users will be able to tie SEN accounts to three Vita systems, or three PSPs, or a three-hit combo of Vitas and PSPs - go crazy with your combos, the world is your portable oyster.

As for the downtime, as usual the PS Store, Home, and account management go offline, but if you've signed into PSN sometime in the last few days it won't affect online play or apps.
