We do know that it will be based on "30 Rock," in honor of the show's final episode coming up Thursday night. And it makes sense, if you recall the episode showing Liz Lemon with a treadmill and an ice cream sundae going at the same time.

Ben & Jerry's has announced it is releasing the new treat, but hasn't given out the details as of yet. The "30 Rock" themed flavor will be announced in New York City by co-founder Jerry Greenfield.

Usually new flavors are released in the springtime, but this new one will be available in Ben & Jerry's stores in February, and then in grocery stores later.
