Well, you will be always be able, i think, to sell 40GB without BC for some 300-350$. And get BC version.
Not all people care about BC.
But well, if you care about BC, you should have already bought 80GB or 60GB when it was available.
If you want cheaper PS3 NOW, get 40GB without BC, if you want PS3 later, buy cheaper 40GB with BC next year.
I repeat: NOT ALL PEOPLE care about BC.
