What news?
The good news is that it is clear that there will be no replacement. That is sad as I love my iMac Pro. Don't want to mess with internal hardware or monitor, price was reasonable as compared to other vendor's equivalent systems at the time.
Now I'm in a quandary. The iMac Pro was midway between the iMac and the new Mac Pro, giving a good price/performance ratio for its specifications. My 18 core iMac Pro with 128 GB of memory gives similar performance as a Mac Pro 16 core for thousands of dollars less, if you include monitor cost, in a small package which fits on my desk and doesn't need wheels.
If the rumored small MacPro will be its equivalent in the cost/performance area, that will likely mean a long wait. Probably at the end of the 2 year transition period. I assume the same for the iMac line, the best performing one will be at the end of the period. Multiple SOCs (?) for high cpu counts, large amounts of memory both for cpu and graphics will require a lot of time to develop. So does one wait a year+ for the small MacPro or ....
