The Asus event at CES will be starting soon and you can watch it here when it does. That will be at 12PM PST (that's 8PM GMT).
Before that happens though, let's take a quick peek at the rumor mill to see what to expect. The teasers from Asus asked "What's your number?" with the numbers 4, 5 and 6 featured in the video, those are presumably screen sizes. A Windows 8.1 tablet, the VivoTab Note 8, is a likely candidate too.
The event just concluded but you can find the replay below.
