BM Micro Panel Repair - How long will it take?

My Micro Panel Shadow control knob just became unresponsive without rhyme or reason. So I got an RMA and send it to BlackMagic in the USA to be diagnosed and repair. It’s been over a week since they received it but I have not heard a peep from them. I called today and all they can tell me is that they have received the panel and it will be another 10-15 days before they will let me know. Is that typically how long it will take to check in and do diagnostic so they can get me a status. Since the hardware just failed itself, would it be even more cost effective for them to just replace the panel?
