Unless they have something new coming soon. I guess they are satisfied with their DSLR lines that don't have much competition.
I've been looking at the mirrorless offerings for quite some time. I really dont see any point in them. They aren't pocketable and not upto the quality level of DSLRs.
If you need to take "serious" pictures, then weight differece is immaterial, so take a DSLR. If on vacation and for occasional shots - P&S like this G1X is the best fit.
The trouble with other point and shoots, is that once you're used to DSLR quality level, its hard to accept their rubbish output.
