Once Google Edition is released, do you think developers will be able to tweak it to make it work on Verizon?
I need it really badly because I can't stand the button layout and all that Samsung bloat (I'm used to Nexus).
I already got GS4.Very unlikely given the different networks (gsm only device will not have the information needed to authenticate on a CDMA network and/or proper radios). The most likely win will be from a port made by the developer community as a flashable AOSP ROM for the standard Verizon S4. The buttons will be identical though on all versions. You might want to consider the Moto X which is rumored for release at the end of summer/beginning of fall or the HTC One which should be available sooner.
I don't think Verizon and Sprint allow unlocked phones onto their networks. I went into Verizon trying to get this and they flat out told me they will not allow unlocked devices. It's why I stopped using Verizon.
