I know what you're saying here, Ade.
I've always gotten the impression they answer such inquiries about future models in that sort of vague manner is because they believe any specific talk of the subject might tend to inhibit the sales of their present model line.
(...in other words they're saying, "Why wait? Purchase your new Triumph today because who knows if tomorrow we'll make what you think you really might want. Maybe we will, maybe we won't.")
