I'm sure they do eventually lose some, but not sure how much. There are many brushless motors out there in your everyday appliances (washers, A/C units, etc), not to mention industrial applications, and it's not uncommon to have those running much more frequently for years. Of course, those motors aren't subjected to the intense sudden loads R/C BL is, but still. I would think that as long as the bearings are replaced and the motor isn't overheated, you should be able to get several years of life.

BTW: Not only heat makes magnets lose their power, but vibration as well...
