Just now finished up re-playing Far Cry, an award-winning shooter from early last year, and it was just as fun the second time through. After doing a bit of digging, it looks like the guys who designed that game are finally getting ready to release a follow-in. Not a sequel, but a totally new game, this time "requiring adaptive tactics and customisation of weapons and armour". Which is cool, as I don't recall a shooter that lets you tinker with the weapons themselves. Should be fun!
