What's the Nordic's plan about BLE 4.1 and 4.2

[ianwirght]

hello,

I have known that Nordic has produced new nRF51 DK which already support s130. But it seems only a demo! What's the exactly plan of BLE 4.1 and 4.2? When can buy the new ble stack profile of 4.1 and 4.2?

Thanks

I'm interested in the "Data Length Extension" for the improved data rate it offers on the S110, and realistically I should be interested in any security enhancements.
