Most of those point to Microsoft bringing a more PC-like experience to consoles, which makes sense considering their PC background. Halo helped popularise FPS on consoles (previously a PC genre), Live popularised online play for console games (previously only done on PC) and hard drives, whilst obvious, reduced loading times and allowed users to download content (again, previously PC-only).
They can also be credited with helping to convince previous PC-centric devs make the jump to consoles (hence the wRPG and Gears points).
I suppose the question is, are these really innovations, or would PC devs with Sony and Nintendo have brought these experiences to consoles anyway? We can be sure even if they did, without MS, it would have taken a lot longer.
