Sigma 120-400mm Discontinued..??

Sent off an order last night for a Sigma 120-400mm zoom. Had phone call this morning from a very polite gentleman saying that unfortunately they didn't have any in stock and Sigma have now stopped supplying this lens. I wonder what Sigma will replace it with... if anything?

Wouldn't hold your breath David!
There are those two 150-600's out htere which effectively replace the 150-500 and maybe the 50-500?
I feel that they may not bother with a something to 400 this time around as the big three make one of their own and a Sigma has to offer something more? Heard it was not a big seller and whatever comes out, if anything will be slow into a Pentax mount if ever it seems...
