At the beginning of the second hour of Raw, the WWE played a Royal Rumble ad hyping the return of Batista as part of the 30-Man extravaganza. This would make Batista the very first confirmed participant for the match.
In the very next segment of Raw, Alberto Del Rio confirmed that he also would be part of the 30-man match. With only three weeks to go, expect more names to be added soon, possibly even tonight.
