Unfortunately the plans are only for San Deigo and Chicago at this time.
I posted a blurb about this on in convention thread.
To sum up, nothing is written in stone yet, but there will be an informal gathering at the Comic Con in San Diego where I will be attending, and details are yet to be worked out, but there will likely be another gathering a few weeks later at the Wizard World con in Chicago.
These won't be full blown cons - they won't even be elaborate - rather these will be a gathering of like-minded fans who want to meet one another while hanging out at two of the biggest cons going.
While this is all vague, I thought it should be brought up now so that anyone interested in attending can begin planning the things they need to plan on their own (registering, travel, hotels) and the sooner the better as time keeps on slippin' into the future.
