Tamron Tease Travel-Zoom Lens for Sony Alpha Full-frame Cameras

Tamron have just released a teaser image and video for their next Sony Alpha full-frame lens. Claimed by Tamron to be "a revolutionary new mirrorless lens offering performance plus versatility", it sounds as though Tamron are about to add a travel-zoom lens to the six lenses that they have already released so far for Sony E-mount. As soon as we have them, we will publish more details, but in the meantime, what do you think the new lens will be?
