Amanda Tapping moves to Atlantis

Ogre writes, Just saw an article over on SCI FI Wire announcing that Amanda Tapping will be making the move from SG-1 to Atlantis:

“Tapping will appear in 14 of Atlantis’s 20 episodes. The new season will introduce a powerful new race, new cast members and mark the loss of beloved friends.”

Somewhat ominous and cryptic. I wonder if this is early confirmation to the rumors I’ve seen circulating that the Wraith will be phased out as the token bad guys? And hopefully the “beloved friends” indicates the demise of Rainbow Sun Francks and that abortion of a sub-plot.
