New Tamron lens for e-mount: 18-200
i wouldnt be surprised if this isnt just a rebadged sony 18-200. sony owns 11% of tamron and some existing sony alpha lenses are just rebadged tamrons.
Though you might be interested:

Not as sexy as the Sony 18-200, but has macro capabilities (50cm minimum focus at every focal length) and might be a tad cheaper. That said, availability and price are unknown at the moment.
