You can watch a recording of the GB live video even from this morning here
I can't say I'm happy about this news at all, especially as someone who has been paying for a GiantBomb subscription. As said above, the reason I liked GB is that they had a small, personal, indie feel to everything they did. I've kind of considered GameSpot to be a dying juvenile-oriented site for the last...10 years or so, so the fact that GiantBomb is now mixed in with them is not a good thing to me.
Also in cool news about the Testet guys. I always thought they were the sort of guys that would fit in well with the Mythbusters anyway.
