If you are tooled up and supplied to build Epic here, then spinning out another line in the same factory, minus a few components has got to be more economical than duplicating the entire facility elsewhere.
If Epic-S comes in between $8k-5k under Epic-X then everything else seems to fall into place. Does RedOne fit between the two Epics or will it be too feature deficient to sit there? If it has the horsepower, or room to add it, RedOne could have longer legs than most would expect.
I know most folks don't want to hear it, but I always expected an Epic to replace RedOne entirely. The only surprise is that it appears "Epic-S" will be that replacement, and upgrading RedOne owners will be getting a significant upgrade in Epic-X instead of an evolved RedOne. In that scenario, everything makes sense to me. Epic-X, Epic-S and Scarlet 2/3 fixed and interchangeable... That's it. The hand machined Epic is an LTD (For Limited Edition).
Will there be both Epic-XFF and Epic-SFF? We will have to wait and see.
