So here's the first online review of a real Leica M8, due to be officially launched at Photokina this year. Looks like it will retail for around USD $5k, or GBP £3k... painful - but not as bad as some predicted.
Released alongside it will be a Tri Elmar M 16-18-21 mm F4 ASPH lens, which will work on film based M's as well. They won't be available in retail until November apparently, leaving a little more time to see actual image files and more review before parting with your money.
It's a beautiful camera - I hope it handles as well as the M7 and that the image quality lives up to the film cameras. The only thing I can't find any reference to is how it allows exposure compensation, hopefully it's a little more useable than the M7's dial.
