Zenbooks, as alleged spec sheets for their successors have just surfaced. According to documents obtained by The Verge, the upcoming refresh will be significant for both the 11.6-inch UX21 and 13.3-inch UX31. Dubbed the UX21A and UX31A, respectively, both supposedly make do with Ivy Bridge silicon (spanning from Core i3s all the way to i7s) which also means a free update to Intel's HD Graphics 4000. Brawny internals aside, most interesting are the optional 1080p IPS panels on both, which should be particularly gorgeous and pixel-dense in the smaller 11.6-inch beaut. Also rumored is the inclusion of WiDi, alongside backlit keyboard decks -- all stuffed into the same svelte footprints as their predecessors. Naturally, there's no word on when they'll land, but you'll know more when we do. Catch the full spill at the source link below.
