At least you can conlude this from what Per has written on his personal Facebook site recently:

Roxette? Son of a Plumber? Gyllene Tider? Try PER GESSLE OFFICIAL on Facebook! This page will close down eventually. Cheers, P.

This page was created in November 2009 by Per Gessle himself. Since March 2010 there is PER GESSLE OFFICIAL SITE, where you can follow Per’s songs of a day and other thoughts. No changing in Twitter or Snowfish accounta at this point.
