I don't think it'll actually change any plans that WWE has for the Vince angle. I'm not sure how anyone could even think that. It's just going to be very, ummm, touchy for them to mention it and I imagine they'll do it in a way that doesn't make much of an impact at all, and after the quick mention they wont mention anything about it again for a long time, not until they mention it on a DVD or some sort of video package or something in the future.
Didn't WWE simply not mention a death or two in the past, simply because they didn't want it brought to the attention of the fans? I forget who it was, or the couple of people it was, but I'm pretty sure there's been a few they didn't mention just because they didn't want the fans to even realize it. Was it Crash Holly maybe?
I don't think WWE would do that to Sherri just because of the Vince angle, but hell, you never know with them.
