ASIC for LTC will not appear unless LTC becomes as successful as BTC.

LTC ASIC's will appear when it becomes profitable for someone to design, manufacture, and sell an LTC ASIC

I agree with both - one leads to the other. I think only a critical failure of BTC will stop the ASICs from coming out.

Yes, ASIC will arrive in LTC once BTC's demand is met..

What demand are you speaking of specifically? The demand for ASICs miners? The public's demand for BTC? All of the above? Tongue
