All that stuff went away when John Romero left,
Romero didn't "leave," he was fired.
This appears to be nothing more than an engine release that is dressed up a bit in order to sell the technology.
Ah yes, essentially the ol' "tech demo" charge, a claim as tired as it is dumb. People say it to sound cool, I guess, but if anyone actually believes it, they simply do not know what a tech demo is. And furthermore, since only developers who publish through Bethesda can use id Tech 5, it would be pretty idiotic to spend 6+ years and untold millions of dollars "dressing up an engine" to sell to buyers who may not exist.
There are a bunch of other engines around that do the job at way cheaper rates.
mfh is privy to how much Bethesda would charge to license the tech? Do tell!
