NBC has announced that they will be bringing back Chuck, Heroes, and Life for the 08-09 season.
The official press release states:

All three series will have major re-launch campaigns next year.

“We are thrilled to be bringing back the high-energy dramas ‘Chuck’ and Life’ for next season,” said Silverman. “Additionally, we will be saving and re-launching our #1 drama and most successful franchise, ‘Heroes,’ so that it will run in all original episodes in the fourth quarter.”

This isn’t particularly groundbreaking news, I couldn’t imagine NBC losing Heroes, but Chuck and Life were in a strange limbo with their orders of a “back nine” put on hold by the strike. It’s good to know that they’ll be back.
