The bulb manufacturers are working on bulbs that meet the new effency standards and compatible to the older ones.
Incadescent bulbs are not baned outright; if they can meet the new standards. Could be a big if.
The CFL; CCFL and LED manufacturers want to push the idea that incandescents are baned outright but they are not.
Though I have seen users in automation forums. Buying cases of bulbs while they can.
