Personally, I’d probably wait for the 16” MBP, then decide, but your situation might be different. I’d be interested in an external monitor with USB-C charging as a companion device for desk use.
A macbook pro in no way compares to an iMac Pro, top spec iMac, or a Mac Pro. No matter what Apple comes out with, it will not compare to a desktop class computer which is what OP seems to be looking for. Strange advice.
OP, if the iMac Pro is the base model, skip it. Go for the top spec iMac with education discount. Despite the better cooling on the iMac Pro, I wouldn't drop 4K cash on a 2 year old machine with limited upgrade paths. The 2019 iMac outperforms the iMac Pro in single core and multi core. You would at least need the 10 core iMac Pro to see some performance gains over the 2019 iMac. And with the recent storage upgrade price drops, the cost of a 1 TB SSD has been halved. Good time to bye if you need a computer now.
And unless portability is a factor, skip the weird MacBook pro suggestions upthread. MacBooks have been unreliable for the past few years and until a product materializes and has been tested to not have the same issues as the others, I wouldn't waste your time waiting.
