A "Q5NPro" is something that has been kicked around for the future, with things like 15m band, fans, higher power, updated LCD, backlit buttons, etc... But it is not on the near roadmap at this point. That's not to say it won't ever happen, but it is down the list because the Nii "short case" just had it's update.
The new Nii short case update is actually pretty substantial under the hood, it shares a lot with the AT-6666Pro already. The differences when operating the old Nii vs the new Nii "short case" are massive especially if you are using it in VFO mode. (FYI- A new firmware is incoming for the AT-5555Nii short case, soon... The main items in the upcoming update are a significant Memory mode change, CW updates, and a new PUBLIC settings menu on the radio. Some of these things come from the AT-6666Pro).
FWIW, I would love to see a "Q5NPro" happen when the radio gets its next makeover... I have always really liked the ergonomics of the 5555Nii. The more HAM focused design ticks a lot of boxes for the PRO market, but still works well for the CB markets too.
