You can see which ETA movements are "current" and which are "phased out" here (scroll down to "Mecaline"):
shopb2b.eta.ch
Interestingly, 2824-2 and 2892A2 show as "phased out" while the Valjouxes (7750, 7751, 7753, 7754) show as current.
Seeing as their main site doesn't show any of the Mecaline stuff anymore I expect the rest of them will be phased out before too long. Within the Swatch Group brands, the Valjoux movements are being replaced by C01 and updated A07 variants that are internal only and not offered to third parties, and thus won't show up on the site.
