When is next Photo exhibit where Nixon may announce new lenses

When is next Photo exhibit where Nixon may announce new lenses

I am hoping for a new version of the 17-55 f2.8 either in DX or FX.
Any rumors about a similar focal length being released?

It will be 10 years since the 17-55 f2.8 Dx was released.

Something in that range (even an f4 constant) with Nano at under $1000.00 would be ideal.

Thanks

Greg
