As far as I understand, all that is "trial" in this is the commercial
success - if it doesn't sell, they'll drop it. In which case I'd rather
expect the resale value to go up!
Now really, are you worried about the resale value of remote you
can still buy new for 160€ or whatever it is? It's not like there'll
ever be a problem selling a working Beo4, no matter which version.
