The 100mm macro lens from Panasonic will be announced on January 8th?

Panasonic is rumored to announce the new 100mm macro lens on January 8th. On a much older roadmap this was marked as having a f/2.8 aperture while on the latest roadmap there was no mention of the exact specs. I go the info about the announcement date from one new source…so let’s hope he is spot on because he claims also to knwo what’s coming after that lens 😉
