ASIC chips for scrypt won't be as huge of a gain margin as it was for bitcoin. The biggest reason is how memory intensive scrypt mining is compared to sha.
Also from what I've heard, no company making ASIC's has actually met their shipping dates as listed, for those who are considering pre-ordering. The first company to accept pre-orders will obviously become rich overnight, so who really knows what offers will be legit or a scam.
Hopefully it does not work this way, or the scam is almost sure (even if only delaying development + production)
