Thinkpad x120e buy now or wait for future?

I have been wanting to purchase the Thinkpad x120e, but I'm not sure if now is a good time, since it was released almost a year ago, and it is the first of it's kind to sport the new AMD e350 processor. I don't know if Lenovo plans on upgrading this soon (since it's been almost a year) and if it would be better to wait for the next gen of this class of non-netbook netbooks. I would like your input on this issue and what you predict for future releases. Thanks!
