Then buy this years filthys... They aren't changing anything on the filthy except the topsheet next year. You'll be happier if you buy the one which topsheets you like best, even if you have to wait a few months to ski them.
My buddy bought new lifes over the 2012 summer, tore his acl on his second day of the season, and finally just skied them for the first time a few weeks ago. You'll be okay.
