Is Sony updating the 50mm 1.4?

I'm starting to think about getting a fast prime to augment my 16-50SSM on my A65. I'd like to be able to use it wide for indoor portrait shooting - I really prefer not to use flash, and indoor shots, even at f2.8 sometimes require going above iso 800, which I don't love.

The Sony 50mm 1.4 is getting to be a bit older at this point - have they discussed doing a 50mm SSM prime? I would want to consider waiting instead of going for the existing lens or the Sigma 50mm 1.4 HSM.

Thanks for any input!
