It seems to me that Star Trek is moving beyond the "only what you see on screen is canon" and on to "whatever TPTB say is canon is canon".
I didn't get that out of the article at all.
Yes, Orci and Kurtzman are supervising the production but unless they aquire the rights to all things Trek and become the actual TPTB, they have no say in the matter.
They wrote the ST XI prequel comics too and that didn't automatically make them canon.
regarding the game footage: Looks awesome!
