He's referring to VP upgrading. Not Warforged. The 3 random bonuses are:tertiary, gem or warforged.

We don't know. I personally believe they are removing VP, but that is a far reaching assumption based off a few Blizzard statements and shouldn't be taken as gospel.
As interesting as that may be I don't forsee that happening, mainly because it is one of the last remaining elements of grind in this game, and having to cap it weekly is beneficial to blizzard (making you stay subbed)
