1. The Kobe 9 Flyknit iD stayed up until the release of the X, or maybe a few days after. I would guess these will stay up until the XI rekeases in February... but who knows with Nike.
2. When the MC released on the 9, it was just another upper option, I.e. asymmetrical. No options were taken...
When I placed my first order for 2 pairs this morning when the iD went live, my arrival date was 7/31. Just ordered a 3rd pair a min ago, and that arrival date is 8/3. The orders must really be coming in...
