"Wrong" Fanon

[stickbook41]

Sorry if this has been brought up before, but is there any current 
speculation on what's going to happen to some of the fanfics that 
operate on any particular theory if such a theory is "proven wrong" 
by future canon?  Like if one SHIP is obviously not something JKR 
had in mind, do the sunken SHIPs that just get delegated an AU label 
or what?  I mean, there are entire websites dedicated to taking 
sides on issues like this.  Some of them quite popular.

I look forward to seeing, after the OotP release, if fanon is simply 
reorganised or if it's turned completely upside down. *grins 
maniacally*

Cheers!
