ASIC for X11, X13, X15 is very easy since they are a linear sequence of calculations, so regardless if 11, 13 or 15 rounds they always happen in the same sequence. 

Quark algo has random hashing rounds so it is much harder to make an ASIC, not impossible but it would be much much more difficult than the X series algos so I do not believe it woud be included on ASIC hardware designed for X series.  I'll believe it when I see it.
