Jimmy Fallon has been a great source of promotion for gaming since assuming the seat of the Late Show. That trend will continue on June 22 when he will show off Call of Duty: Black Ops on his program. That’s some great promotion for Activision’s upcoming Call of Duty game, developed by Treyarch.

Monday saw Kudo Tsunoda coming on to demo Kinect. On Wednesday, Fallon will continue his nerd-oriented guests with Joshua Topolsky, EIC of Engadget.
