had no idea Leica released this! guess I was not looking at leicarumors for a while! it is very cool indeed, I love that this is made of titanium. more stronger and harder than aluminum. density is slightly higher than aluminum. Compared to a stainless or brass versions it will be quite light. Since its stronger than aluminum, Leica would have machined in thinner to match the weight to current version? weight spec on the manual should let us know.
