Buy 20 1.7 II now or wait for Leica 15 1.7?

Hi, I want to add a 'standard' prime to my lens collection. For 2 purposes: 1) low-light indoor usage during parties and 2) taking sharp images for pixel-peeping Unfortunately, I am a pixel-peeper. I don't print any photos but I really enjoy investigation of little details on display (with 100% zoom and dragging).

First of all I decided between Panasonic 20 1.7 and Olympus 17 1.8. I read many, many reviews and looked many photos and I agree that 17 1.8 is not sharp enough (for me). And the second version of 20 1.7 is more beautiful than the first one, IMHO, so I am almost ready to buy it regardless of slow auto-focus.

Now I'm reading some rumors about Leica 15 1.7 which was announced on 2014 for GM1 and wondering if it will be much better than 20 1.7 for me. Both focus lengths have pluses and minuses when using in small room, so the decision can be made only by unknown sharpness, price and availability of the new lens. What do you think?

These are pretty different focal lengths in my opinion being 30mm vs 40mm equivalents.  While 40mm is close to normal, 30mm is fairly wide.  If I were you, I would purchase based on focal length and not look back.  If you're not sure if the Leica lens will be to your liking, you could always try the Panasonic 14mm lens for cheap from ebay (~$160 USD).  Much less of a gamble should you not like the focal length...
