I wonder when the developers will consider they got enough coins with their ASICS and finally proceed with the fork.

Before you take your pitchfork just hear me out:
1) They chose Scrypt-N over any other algorithm, even though they have been warned that scrypt-n is easily mineable with asics and they have been shown many Vertcoin posts (a scrypt-n coin) about people using asics.
2) When people complained about Asics, they kept saying it is just FUD, and ASICS can't and won't be able to mine scrypt-n.
3) After a reddit user posted detailed instructions and screenshots of how he is using his ASIC to mine scrypt-n, the developers said nevermind, it is just one guy, we will bump the N factor or change the algorithm.
4) After so many days, with a lot of ASICS on the network, they still do their best not to bump the N factor or use a well known developed algorithm and chose to develop their own algorithm(which of course will take a lot to develop,test and implement).

Take your own conclusion: incompetence or just buying time to make the most of their ASICS.
