I hadn't realized that they've removed the Rocket line from the site - that's a pretty ominous milestone. The speaker that's "coming soon" to replace it is still just a rendering and a promise of matching center and surrounds that aren't even that far along. History suggests that getting from the rendering stage to having stock on hand in Colorado can take anywhere from a year to five years (assuming that the product isn't outright vaporware).
The X-series isn't fairing much better. There are exactly two speakers left: X-Static and X-Voce. The b-stock offerings include some shadows from the past (X-SLS and X-Sub), but even that is pretty sketchy.
The LS4 cabinets haven't even been built yet. They estimate ~3 weeks until they have stock. That's likely to be more like ~2-3 months if you are optimistic, or more if you are realistic.
The ELT525 line looks like it may be on the way out, too. All the rosewood is sold out, leaving just the cherry finish. Their claim that the current ELT525 sale is to make room for new products seems pretty questionable, since the ELT525's are small compared to the Rockets and many of the X-series stuff that they used to keep in stock all the time - with Rockets out of the way, limited LS inventory (a few sets of B-stock cabinets), and only two X speakers still available, there should be room to spare. I wonder how long that product line will be around?
