Iphone 5 now or wait for a year?

I'm not sure whether i should get the iphone 5 now for about $600, or wait until my upgrade in February 2015 which will probably have the iphone 6 by then? I'm a pretty impatient person and my current phone is pretty bad.

Get the iphone5 now
Btw the new is suppose to have a 3D screen it comes out june 2014

Get it now otherwise youll be stressed out till 2015
