Eh, the idea that the current generation doesn't stack up is already the mindset of the fanbase, whether WWE pushes the new guys or not.
I don't think it's a matter of "sending a message", more along the lines of it is capitalizing on things that the fanbase would actually want to see. I've got no beef with Rock v. Brock.
As far as Jericho goes, I'm glad that he's enjoying success outside of WWE, but it is frustrating watching him come back for just a couple months, only to leave and go on tour again for a band that nobody gives a crap about. I want to watch Jericho wrestling, not touring with a rock band.
