As awful as it is, it's probably best that it failed now. They're bound to move the 1DsIII to the discontinued state within a few years, at which point you won't be able to get a new shutter. Dying now might end up meaning a longer life in the end, as you've got a whole new shutter to work through.
The 1DsIII is already discontinued (around the time the 1Dx hit the streets). I think you mean they're bound to move the 1DsIII to the end-of-life/end-of-support state.
We're a Canon/Profoto family: five cameras, sixteen lenses, fifteen Profoto lights, too many modifiers.
