Patriot would certainly be a lot easier for Marvel to subsequently dust off in the comics...LOT less dust than Rage.
But between the "not of this Earth" line and the weird-looking tech that can be seen on Richards' arm (I'm pretty sure that's his sleeve) at 2:16, I'm thinking his identity might not be something we can determine from these clips alone. He could be Nova or Darkhawk for all we know, with that thing on his arm acting as the Wolrdmind/amulet.
I've also seen the tech pointing to Battlestar.
But I'm more and more keen on the idea of Josiah X, who has the strengths of using Patriot, without aging Patriot out of a future Young Avengers project.
