From what I've heard from one of my group-mates who has contact with the people running the convention, they have already laid out plans for the next Rose City Comic-Con, so yeah, it's definitely hear for the foreseeable future.
I was at the convention as well. I was with the group at the Rebel Legion/Imperial 501st Legion Kashyyyk Base/Cloud City Garrison booth. I was there most of the day on Saturday, but after hurting my ankle I wasn't able to make it back on Sunday. Thankfully I got in for free because I was part of the group, so I didn't have a wasted ticket day...
