Heroes Spoilers Galore: Future of Kristen Bell, Sylar, HRG and More!

Our many thanks to Kristin of E! Online for the following Heroes spoilers and scoops. Among the items she informs us of are:

• Sources say Kristen Bell will not be a regular this season. However, she will appear in a recurring fashion, most likely for five more episodes.
• The only new regular is Cristine Rose as Mama Petrelli, who has a lot to do with event this season.
• Sylar is going to start working with H.R.G.

Interesting tidbits for sure. It's too bad Bell won't be on the series full-time. Seems like the show never used her to her full potential, doesn't it?

As for the Sylar and H.R.G. pairing: what could they be up to together?
