Leica - Digital-Modul-R
instead of coming out with a typical DSLR, leica have implemented a modular concept by introducing a digital back that can be used with its film SLRs [R8 or R9]. this idea is not new though, being used on medium format cameras. potentially, this also may mean upgradibility, with users changing to a newer digital back while retaining existing lens and body. it's not going to be cheap though, since its a leica.
