So the spec for 12-40mm has been out

- Manual focus clutch mechanism
- 20cm minimum focusing distance (maximum magnification of 0.3 times, 35mm equivalent 0.6 times) throughout the entire zoom range
- Dust-proof drip
- Filter size: 62mm
- Total length: 84mm, maximum diameter 69.9mm
- Weight: 382g

Panasonic 12-35mm F2.8
- 25cm minimum focusing distance (maximum magnification of 0.17 times, 35mm equivalent 0.34 times)
- Weathersealed
- Filter size: 58mm
- Total length: 73.8mm, maximum diameter 67.6mm
- Weight: 305g

12-40mm being being more larger/heavier than 12-35mm and come without OIS, should make Pana user and maybe some Oly user sticking with 12-35mm instead for the size and without looking ridiculous on their camera.

Though the magnification of 12-40 screams Macro to me, that is even higher than Voigtlander's 0.25x/0.5x magnificaiton which I found to be plentiful for my need without getting dedicated Macro lens.

I've held off buying a pro zoom until now, as I've been waiting to see what Oly will bring to the table to compete with Panny's 12-35 and 35-100.

Even though I'm an Olympus shooter, I'll probably end up buying the Panny 12-35 based on these specs.

There are two main reasons for this:

1) The Oly is 77g heavier, which is a significant amount.

2) Its filter size is 62mm, whereas the 12-35 takes a 58mm filter. I already own several 58mm filters, as they are compatible with my Oly 40-150 ED and Oly 75-300 II. I'm a big filter user, and am a bit annoyed at Oly's inconsistency with filter sizes. They are using 37mm, 46mm, 58mm and now 62mm. There may even be other sizes - for example, the original kit lens used a different filter size, I think.

You forgot Oly 9-18mm and 12-50mm that use 52mm filters. Speaking of filters I'm pretty sure one would be able to use 58mm filters on 12-40mm for most FL except the widest ones.

Oly 9-18mm can use 46mm filters with 52-46mm step down ring, that is if FL is 10mm or longer. Vignetting only can be seen at 9mm through the middle of 10mm range. 12-50mm works fine with 46mm starting from 14mm FL.

Besides, filter sizes will only increase over time as m4/3 gets more high quality (i.e. large) lenses.
