Zesto audio offers upgrade for Ph-1

They currently have offered the Ph-1.2 phono stage and are offering an update on the Ph-1. I don't know all the details but the upgrade is 1500.00 which includes shipping to Zestos. I believe the upgrade has to be done through the dealer network.
Why would someone invest $5800 in a unit that can be bought for $4700 new? Seems like a very pricey upgrade. I guess the used prices of v1's are going to plummet now.
I have one but I think you might be right.
