Zach's coverage from last year was awesome.
There is WotC specific stuff at
you tube.
I found
OboeCop's youtube coverage of GenCon.
Mini specific news at
Table Top Gaming News, with photo's and video.
Ogre Cave has a bit and will probably have more.
This Just In from GenCon is a podcast from RPGnow.
I think some here have mentioned these places already and I think there are quite a few more. Some of the other blogs out there have good stuff.
I always wonder why GenCon's web site news and info about the con is so abysmal. I think the only news about gen con on the site is in the
community section but there doesn't seem to be very much. I suggest a news blog at the very least. A podcast and/or a youtube feed would also be a good idea.
Note, I'm not knocking the running of the actual con. They do seem to do a bang up job with few actual employees. I also realize that they can expect others to cover gen con and might not have the finances or manpower to do it themselves. I just wish they could and would do a more comprehensive job of coverage. Maybe it hasn't crossed their minds to do so?
Edit: just thought, maybe a blog or web page aggregating the news of gen con from around the web? Is there something like that somewhere? Here on Enworld? GenCon guys, are you listening?
Second Edit: Also there is the
thread at rpg.net.
