yeah the main improvement i have heard about these is a firmer heal. Im excited to try them out when they are released, someone a few pages ago is a tester i guess and tried them so you could ask him his opinion. The 1s where a little too cushioned for me, i prefer the nano 5.0s personally even...
I haven't heard anything about an official release date, but should be early 2016. Im sure the Metcon 1's will drop in price but i doubt it will be too significant anytime soon.
