As long as they don't kill the local network abilities, I won't mind. Besides, I already have a 5000 series, so it's not like I'm going to lose anything.

I never used Commercial Advance because it was always buggy. Although, reports from ReplayTV users on AVSForum are that Commercial Advance is much improved in the new 5.0 software, which is currently rolling out to the 5000's based on serial number. And as for internet show sharing, I would find that useful if I had the unfortunate luck of missing a show due to some unexpected circumstance (power outage, etc).

I'll just sit back and watch what happens.
