Aren't Cryptonote the dev group behind bytecoin's codebase?
It's hazy (the relation between cryptonote devs / bytecoin devs).
In any case, I think we can fully expect a raft of cryptonote-based alts with various improvements, some of which will shape up to be Darkcoin's main competitors. It's worth keeping close tabs on MRO and the rest. I suspect it won't be the bytecoin devs themselves who create the killer cryptonote coin, as they seem to lack any marketing sense whatsoever.
I'd take the real devs over the cloners for a bytecoin 2.0 upgraded coin. Cloners would probably be best for fixing the peripherals (gui's, logos, branding, etc).
Did you read gmax's comments about coinjoin and how everything being done here is a "sales pitch".
I like skepticism but Darkcoin isn't even marketing or selling itself. It attracts attention by virtue of its characteristics. Always has, since the start.
