Basically what the title says, after HTC got denied the Nexus 3 and following their failures with the thunderbolt I see no reason this could be too far off.
Qualcomm said the krait would debut by the end of this year and I don't think they have very many other options. Plus having krait on the Rezound would surely give it a leg up against the Nexus due to power issues and having onboard LTE. It would also allow them to release an LTE device with the same form-factor as the sensation which everything is pointing towards, could be why they've kept such a tight lid on the actual specs of the device.
