AirPods Max buy now?

Hi. In Germany, AirPods Max cost around 570€ including VAT. You really can't get them any cheaper. I recently bought a used one for 405€ from a reputable commercial seller with warranty. I'm sure that Apple will release the second gen APM this year. Do you think I can resell mine for at least 300€ in a year? Should I return it and wait for the new release?
