For those of you curious I emailed Hashfast again about the MPP and this was their response,

In regards to MPP - other than knowing that for Batch 1 it will be the
full 1.6TH, I am unable to release any more information of this for you. I
do hope to get something out shortly.

We want to make sure we send out the best MPP possible for our clients. Once the shipments of MPP boards begin to ship we will let our customers aware of their shipping date.
