I've claimed the 17mm. Oly Australia have acknowledged the claim but say up to 20 days to process it. Hopefully I get it a little quicker than that!
I see this deal as entirely a hook to keep users in the system. They clear Em1ii stock, and with a Pro lens now in the kit they probably think users will be more likely to look forward to the next Body upgrade. The more top glass you have, the bigger decision it is to leave a system.
