X11 does nothing to purposely obfuscate how ASICs can be developed for it (as opposed to scrypt-n).
Scrypt n doesn't obfuscate anything, it just makes the on-die RAM requirements financially/technologically unfeasable.
ANY algo (or algo chain like X11) can be quickly changed to instantly obsolete an existing ASIC design, if the devs are willing. The LTC guys could have done it with zero fuss and majority community backing, but they had already sunk millions into ASIC pre-orders, so came out with a load of blathering bollocks instead.
