"the nearest apple store is in Jacksonville Florida which is about 3 hours from tallahassee."
You shouldn't have to go to an Apple Store to see an iPhone 5. I believe they have display models at Verizon and AT&T stores. I could be wrong on this as I haven't been in to a Verizon store for quite some time, but I can't believe that almost 2.5 months after it's release it wouldn't be on display at it's 2 major sellers.
I would go for the upgrade. IMHO, even IF they come out with the i5s it won't be until at least the summer. I also don't think there will be any "major" updates. They will probably just say it's got a better chip, better camera (maybe getting rid of the purple haze problem). It's not going to have a bigger screen, etc. But the i5 already has a great camera and is extremely fast. Not sure you would be able to notice an update to either, to be honest.
Like someone else above said, my guess is the "iPhone 6" will be the one that gets the big update. Probably larger screen, which is really what most people will be looking for. If you get the i5 now, you'll be close to being able to upgrade to the i6, which would most likely launch in the Fall of 2014.
Until then, enjoy a great phone in the i5.
