X11 asics will come if sCrypt asics will turn out to be successful. As it is, X11 already offers a higher hashrate than sCrypt for lower power consumption. Asics for X11 might just not be worth creating. And, above all, as I continuously stated whenever I had the chance, it appears that sCrypt asics might just have killed sCrypt. Most miners, instead of buying the new asics, chose to move to a different algo.
So, bottom line is that for SHA-256, ASICS were a success; for sCrypt, not so much. I'm guessing that the next ASIC that comes out for a new algo (probably X11) will fail horribly.

Hefty is a wonderful thing. The reason this coin is dying is the same for every other coin. You will need a very strong integration in the community and, beside this, you will have to find a way to integrate it in the environment outside the crypto world. This is pretty hard to accomplish, but if you manage to do it, the coin will flourish.

With almost every coin, and probably every algo out there, there is one enormous problem: the distribution. Most coins use PoW. It's biggest flaw is that the more Hashpower you have, the bigger your reward will be. This should not be happening. The amount of coin a node should be able to gain should not depend on that node's hashpower, and it should be limited for the given unit of time. This will ensure a fair distribution and will also make the development of dedicated mining equipment superfluous. Solo mining will be encouraged and more and more people will come to claim their fair share, thus helping secure the network. There will be no pools, no huge farms and no useless dedicated hardware. People will mine using their phones, laptops, PCs, and will do this while enjoying other activities on their devices. There will be no need for specialized software, because mining with the wallet will be sufficient. This will be the future, and that future is not far away.
