No successor to the X30?

[M'Collo]

I like my X2-s and my 3 lens
But I  am also a bike traveller on MTB in autonomy (Iceland, Norway, mountains etc… ),  nordic ski touring... etc..;;
So, my dream is a light,robust and versatile, a true « adventurer » camera, ‘baroudeur’ in french.
- bigger x-trans sensor than X30 (Aps-C, 4/3 ?)
- zoom f2.8 , small range i.e.  30/32 -> 70/80 equiv. to avoid weight. It’s sufficient for classical portraits and landscape in such trips
- resistant to dust, rain and low/hight temperatures (waterproof is not necessary)

At present, there is none such camera on the market and, I beleive? a lot of potential purchaser.
