My upgrade is due in August, so it's a bit too early to decide. My first choice would be this rumored Motorola/Google X phone (provided it is essentially a Nexus device with regards to software updates). Barring that, I'm definitely interested in seeing Verizon's alleged variant of the HTC ONE. If it's as good as the ONE, then that will be a strong possibility. The newly announced "rugged" Galaxy S4 is of interest too.
With those two phones though, Nova Launcher Prime would be an absolute necessity because I really can't stand Sense or TouchWiz.
