I wouldn't hold my breath on a new perpetual license version of Office...who knows when it will appear and you can only install each copy on ONE Mac, which for any of us with more than one - or 3 or 4 - in the household makes no economic sense whatsoever. Plus you don't get OneDrive with the perpetual license, and with 1TB PER PERSON (up to 5 people) that's a pretty good deal. I pay almost twice that just for a year's worth of 2TB of storage at Dropbox (need it for work with clients etc.). So I've reluctantly acceded to the subscription model for office software.
And, I suspect I'll finally cave on Lightroom/Photoshop too - right now I'm using my son's subscription, but try as I might, I can't find the energy or the time to move over 100,000 photos to Capture One.
