If it's true about him arguing/flipping off Cole last night then he only has himself to blame. Remember how they worded ADR's release as being "unprofessional", if you're using obscene gestures or arguing with a commentator out of storyline, in front of the fans ("BAH GOD LITTLE JIMMY SAW THE BIRD...HIS LIFE IS RUINED") then WWE doesn't have much of a place to go other than to fire him cos a lot of the arena would have seen it.
There is a cynical thing that I think could have come into play as him being on "thin ice" and god forbid it ever comes out as the case... WWE and Stephanie and Trips in particular have kinda taken over the Conor's Cure thing now, with their own charity... Roberts recently posted a very touching and blog informative blog about how HE was the one who discovered and introduced Connor backstage along side how great WWE were with him etc.... wrong toes to tread on there buddy. Steph has kinda taken over that role now as the "one" behind it and spun it with Bryan...like it or not... but his dad will remember for sure.
His release is harsh but no more harsh than ADR getting F'd over... WWE is in this phase at the moment, they embarrased themselves over Emma and ADR so they are cracking down on stuff.that iis easy to convict on... by the sounds of it, Roberts left them no wriggle room and was an easy "cut and dried" fire once he'd made the mistake.
They are also cutting a lot of "older" talent... Mark Yeaton, Josh Matthews now Roberts... it could be nothing more sinister than they want to go a different direction or to cut costs. But he didn't get the normal "nice goodbye" the said they are "not renewing AND released" so it seems there is more to it. It doesn't hurt for them to send a message to the rest of the roster that however pissed off, frustrated or annoyed you might get with someone, the company or even decisions made... you tow the line without complaint...or someone else will.
He'll go to GFW without question, no brainer for their opening show...I can even see him as the US/English ring announcer alongside the NJPW one.
