Is this whole thread a joke? You seem to have come to the conclusion that the Mac Pro is almost confirmed to be abandoned!? It hasn't even been 3 years since the release of the latest Mac Pro, let alone 4 years. Of course they haven't given up on it! They don't see a Mac Pro as their $3000+ machine to outdate every year by introducing a new model. Apple sees the upgrade cycle for Macs to be around 3 - 4 years, and give that it hasn't even been 3 years, expect an update later this year or at least within the next 12 months.
Of course it would be good for those of us thinking of getting the Mac Pro now or half way through the refresh cycle, but that's not the point. Any update they make would have to be significant in almost every aspect in order to appeal and be a worthy upgrade over the previous gen. Right now a new model would be significant due to the advancements made in the last 3 years (or as you would like to refer to it, "48 months").
I am not saying I like Apples approach, I don't and agree with you that it is very disappointing, but that's how it is.
