Not to be expected any time soon, but it looks like a possible 600cc triple might be in the works for MV agusta. I still don't know that I'd ever find one for the price I like to pay for bikes, but it would definitely be high on my list as MVs have always been my favorite. A 600cc brutale in the general price range of a triumph street triple would just be too much for me to handle. I would hope it would be closer to the 675-700cc range, but I'd be willing to compromise for a midsized MV.
