McIntosh MP100 update?

The MP100 is about 5 years old now and many online stores are out of stock. It’s on my final list of phono stages but I don’t want to make the mistake of buying right before an update is released. Anyone heard of an update being released or is it just the shipping woes causing it to be out of stock?

FWIW, my final two phono stages on my list are the MP100 and the Luxman E-250. I have dreams of an all McIntosh system one day so the MP100 is my top choice for now.
