Other than the Street Triple, we probably won't hear about anything else until October from the dealer's conference.
If your dealer doesn't go, I think they have the option of sending someone else as a rep.
Personally, I am almost willing to bet that the "other" bike is the Rocket III Tourer. Unfortunately, Triumph's idea of a tourer is just hard saddle bags, windshield and single head light (no trunk, no queen seat, no full fairing with lots of gadgets).
