It's actually pretty impressive, they do show actual stuff (for example high-details Crysis multiplayer with one player on set-top box and another one using browser plugin on low-end notebook).

About latency: I was also very skeptical, but in principle it could be doable if they would deploy servers also locally (it can make economical sense for dense urban areas). Google already does this.
I tried to ping around to check latency limits: even across Atlantic I could get to around 30 FPS roundtrip. For servers that were few hundred kilometers away it was ~100 FPS and for my ISP it's ~1000 FPS.
