Get 17mm F/1.8 or sell my whole OM-D kit?

Hi guys,

I've been using my OM-D since last april and been avidly taking a lot of pics with it.
I tend to shot my pics in normal focal length (around 30 - 50mm in FF actual length) and 35mm seems to be the sweet spot for my need. The only problem is... I only have one lens to accommodate that focal length which is Olympus 12-50mm lens kit which come with OM-D.

I've been looking forward for Olympus 17mm F/1.8 lens and thinking to get it asap. 
But since my last trip to Japan, I had a chance to bring over my friend's Fujifilm X100 and been taking many pics with it along with my OM-D.

I must admit, I'm impressed with the quality of JPEG out of X100 - there is a charms on the pictures rendered out of Fujifilm camera and I've taken many RAWs with my OM-D, unfortunately I'm not capable to create similar look and feel to X100 jpegs.

On the other hand, X100 focal length is matching my criteria for a travel camera and also, i'm tempted by XE-1 on my visit to Yodobashi Akiba in Japan.

Then again, there is the new Sony RX-1. 
(I haven't had a chance to try this out, but based on the reviews and feedbacks in this forum, I think it's quite remarkable)

So should I sell my OM-D and my whole kits : 
- Olympus 12-50mm kit lens
- Olympus 40-150mm
- Panasonic 14mm + Wide angle extension
- Voigtlander 25mm F/0.95
- Olympus 45mm F/1.8

or just add a Olympus 17mm F/1.8 lens and be happy with it?

I understand i will miss the flexibility of ILC if I go toward Sony RX-1 or miss telephoto capability with Fuji XE-1 path.

But in the end of the day, I would prefer to bring one lens for my future trip.
