Not really, no. I don't think I'd visit less either. I still keep track of several series' on this site, e.g MovieBob, The Big Picture, Extra Credits, Lisa Foiles, the occasional Unskippable and Daily Drop when it intrigues me, and of course, the Escapist magazine itself.
I would be very sad when it discontinues, but no, I wouldn't leave. The forums over here are one of the best i've seen.
The Escapist WILL suffer from the lack of newbies coming in though. Zero Punctuation is the main attraction.
