When will Lenovo refresh the T-series laptops?

[x509]

I have this old, tired T530. I travel a lot in my job and this machine takes a beating, what with all the plane rides, hotels, when I drop my laptop bag, etc. So I want to replace it "in the next few months."

What I really want to do is wait until the next releases for the T-series, not buy a product that will be replaced sooner with something newer and better.

All opinions welcome.
