I have been following the X32 development since its release (from an engineering standpoint).
When the product was released, it really had no competition in its price range. Over the last 5 years, others have stepped up to the plate and offer compelling products in this price range as well.
The Analog Devices SHARC 21371 that the X32 is based on has just recently been rendered "old" IMO by the new generation of SHARC processors that are available.
My guess is that the new processors (215XX), having a whopping 1800 MAC (multiply-accumulate) units compared to the old 21371's 532 units, along with nearly double the clock speed, will perform more than 4x the 21371.
This is worth the engineering effort for an upgrade IMO; however, it is likely going to take another couple of years to be ready for prime time.
In that period of time, I also suspect that Behringer will release the long awaited (and mostly forgotten by most) V3 firmware to add spice to its X32 line in the interim..... at least that is how I would go about it.
The best way to make money on a product is to design it well from the start (Check), re-use the base technology across many products (Check), then utilize it as long as possible by keeping the feature list up to date while you are working on the next big thing (We will see if I am right or not).
I am very interested in a V2 X32, but I don't expect to see it for some time yet.
It is a testament to the original X32 design that it has taken over the market in its price range (which it created single handedly) and is still arguably the most feature rich product in its class despite several releases of products from competitors.
