Well there's a few new playlists that offer more competitive settings. Like Team Throwdown uses v2 settings which is BR starts. Next week, a map pack will be released, and it will contain 3 small-medium sized maps. TU is also supposed to be released soon.
No, it is a buff. 343i just announced that the boltshot now has lock-on functionality, the burst functionality is now fully automatic, the weapon has unlimited range, and it will be the new starting weapon for all playlists.
They have also announced that the DMR is now capable of stun-locking.
Reportedly, Halo 3 playlist population has had a massive spike recently...
