The Coda Elite was downgraded in 2008 from 631 to the same 520 as all other Coda models have always been - I do not expect that situation to change soon.

Like most "manufacturers," Jamis outsources production. I suspect that's Kinesis, as they are behind so many other brands. It's an enviable position, being unable to meet demand with production, but I think that's the true position - there simply isn't enough production capacity available to build enough frames for everyone. There are, of course, second-tier manufacturers, but sustainable and repeatable production quality over a long production run isn't as easy as it looks. Not and remain profitable, anyway - bicycle frames don't lend themselves easily to robotic production. And as corwin mentions, the trend (and production shift) towards aluminum/carbon has impacted steel capacity, a situation which isn't going to get better soon with steel making a comeback.
