Will it be Vertcoin, Darkcoin, Hirocoin or maybe Quark?

Scrypt-n could become unprofitable for gpus if difficulty rises.

Don't know much about Quark, heard some people mentioning it though, any info?

IMO X11 looks like the most likely choice (Darkcoin,Hirocoin). What do you think? Leave your opinions below.

The reason that guy would be abusive is that he either just purchased a bunch or gridseeds or is a reseller.

Gridseeds are about to be the new blockeruptors but with the shortest shelf life in history.

If they can be effectively copied and made at around the price point you stated or just sub 100 then that's fine, and anyone with a future interest in scrypt should hope for that.
