2650 KV is similar to the 2200KV, but not. Shorter can. It is coming soon. Can't even try to give you a date, but not too long.
Are they similar in amp draw to? I´m getting one for my buggy soon but I haven´t decided if it´s going to be the 2650kv or the 2200kv. If I can cet better runtimes with the 2650kv I´ll probably get one of those
