There's not a big difference between The Verge & Engadget. I've compared them side by side in two different browsers. The Verge is a bit more colorful, Engadget tends to have more dialog updated a bit more frequently.

I usually have Engadget and Verge open at the same time. I stick with one but if the updates get infrequent or it gets buggy, then flip over to the other.
CNET does a good job. I watch them for the Nexus 7 and WWDC12.
There is a user on Ustream 'claiming' they WILL have a live feed on Wednesday.
I messaged him (via iPad app) and he replied, and I quote - "we have experience in obtaining feeds"
Here's a screen shot of the app, with my message and his reply, at the bottom:

Was the stream an actual live video feed of the event or was it only a live blog?
