It's sarcasm, more or less, about how most people supposedly know all the new features of WOHD.

"Two new heads-up displays? Oh, they're from Wipeout 2097 and Wip3out. Yeah, I don't have a source for this information, I just know already."

Kind of like how "Wipeout PS3", the one after HD, supposedly runs on some form of the MotorStorm engine because some blogger said so.

Then again, I could be reading into this too deeply...o_o
