DIPs have been dead for a long time, with only a few exceptions. Replacement parts, hobbiest markets, and some optocouplers with huge spacing requirements are the only ones I can think of off the top of my head. RoHS requirements were one of the final nails in the coffin, but even before that the material costs were really eating into profit margins - especially for the larger microcontrollers. For the older standard parts, I think RoHS requirements forced die redesigns, and manufacturers didn't want to pay for an obviously dead trend, so a lot of old packages got dropped then.
