Maybe they will be released with the rumored Sony a500 and a550 DSLRs.
At the PMA 2009 show Sony showed 6 different prototype lenses: a unknown super-telephoto lens, DT 50mm F1.8, DT 30mm F2.8 Macro, DT 18-55mm F3.5-5.6, DT 55-200mm F4-5.6 and a 28-75mm F2.8. As of today all of them are released except the super-telephoto and the 28-75mm F2.8 zoom lenses. The question is - will there be another DLSR (high end) released with those lenses?
