Upgrading on Verizon

So I have a 2 year contract with Verizon ending sometime in late Spring of 2013 and I am hoping to get the iPhone (5) when it comes out this fall (Sept. 21st or whenever). Would I have to pay an early termination fee or is there a way to upgrade for less money while staying on my 2 year contract. I read something about a $30 upgrade fee but I'm not sure if that applies to me or not. Thanks in advance.
