Lenovo Laptop Refresh

I am looking at getting an x200 for use at college next year but I am weary of getting it and then something brand new coming out right afterward. I know the technology industry moves at a fast pace but if I need to wait a month for the new model I would be willing to. I have done a little research and it seems that lenovo seems only to refresh and redesign its laptops when Intel release a new platform or processor. So I ask is there anything in the rumor mills to be released this summer ( i want to order no later than july 31st). Thanks for the help.
