Oh dear, I very much hope so. I am waiting for this eBay dumping day to finally get one of those babies myself.
It will be the last one with bootcamp, the last one from Sir Ive, and the last “Non-walled-garden” machine with more of a decade of usable shelve life just like the cMP 5.1.
To be honest, I very much doubt that there will be any Apple Silicone Mac Pro in the foreseeable future. Apple will not be able to pull a Xenon class home-brew CPU out of their hat for such laughable, tiny, global, Apple Exclusive quantities for humanly possible price points. Get ready for RED price tags...
