Is strange that this announcement would happen right now, as Harvick, and possibly Ryan will both be 'lame duck' status for the entire season next year. Usually that doesn't bode well for performance.
This is from ESPN article -
Under Stewart-Haas' plan, sources said, Harvick will drive a fourth SHR Chevrolet, teaming with Tony Stewart, Ryan Newman and Danica Patrick to form a four-car stable.
"Stewart-Haas Racing's driver lineup is all set for 2013, but if you're talking about 2014 and if Kevin Harvick is available, that's something the team would have to look at," SHR team spokesman Mike Arning said. "Any team in this garage would do the same.
"From the moment Stewart-Haas Racing was formed, becoming a four-car team is something it's been striving for. They have the infrastructure to accommodate a fourth team, and if everything aligns properly, it's something they'll do. So, if a driver the caliber of Kevin Harvick is available, it's something they would pursue."
