They're in love with that ruddy twin aren't they. I personally found it a rather soulless brute when I rode one but regardless of that, it will never be a Bullet - a Bullet is a single, not a twin. I'd rather they found a way to make a bigger (500?) air cooled single but the EU restrictions are such that this is unlikely, in that case, a water cooled big single (so make it a 650 while you're at it, hell, Kawasaki can do it, why not RE?) is better than a twin. As we've seen in the past, balance shafts can be used to do all sorts of things, from smoothing out all vibration to providing a particular sort of vibration.
Keep the twins for the twins, keep our Classics/Bullets singles.
Of greater concern is RE's mindset of producing a gazillion models - surely that's going to come back to bite them in which case, we're all stuffed.
