Were we expecting any new hardware from ASUS? Items we've seen but have not shipped like the Qube and Transformer Book spring to mind immediately, but they're not a direct match for this pic the company posted on its Google+ page earlier this evening (Update: we replaced it with the final pic.) It's inviting any and all guesses as to what's in store and promises a device reveal tomorrow, so your period of eager anticipation will be (thankfully) short lived. Judging by the comments it might not be anything we've gone hands-on with previously, but the image reveals that spun-metal aluminum look we've become familiar with on ASUS' tablets and laptops lately. Beyond that, the oddly squarish aspect ratio draws immediate comparisons to the 3:2 Chromebook Pixel, but until it's officially unveiled we'll leave the rest of the random speculation up to you.
Update 1: The smart money so far is on its Varidrive media dock, which appears to match the dimensions and spun-metal look nicely -- we'll see what it really is tomorrow.
Update 2: Well, ASUS has relieved the overwhelming tension on its Google+ page by announcing a new... DVD writer. It does strongly resemble the aforementioned Varidrive dock with its spiral brushed aluminum look and the outfit claims it's the world's thinnest at 13mm. Check the second source below for the reveal.
