A source sent me a couple of info about Tamron:
Tamron mentioned that they will only be making mirrorless lenses from now on! I asked if they meant like Canon, but they said that they’re all in on mirrorless and fully committed (unlike Canon).
Tamron also mentioned that some of the previously rumored lenses had their release dates delayed, so we’re getting less lenses than expected. They also expected the 70-180 to be finished by now, so that’s been delayed.
We are likely to get some info about the exact lens price and availability around the CP+ show start on February 27.
