Yeah, it looks like it'll be a really versatile little light. I emailed them about its availability and they said they couldn't be sure, but to check back on their website periodically to see when it becomes available. They didn't say anything about price though... Just as a guess, based on its feature set and output, and that it's a Fenix, I'd guess it's going to be about $60 - $70.
I've already bought two Fenix lights in the last month and a half, an E20 and a L1Tv2 and really like both of them. I keep the E20 in my desk drawer for misc. use around the house, and the L1T in my cycling bag. Once the MC10 comes out, I'll probably give the L1 to my wife, and get the MC10 for my cycling bag. Of course, then I'll need something else small that I can keep in my pocket with my keys, etc. 😗 Probably something like and LD10, but I'm also really liking the Quark AA and the Nightcore PD that uses the single AA is awfully appealing too. 🙂
