Whoopsie boopsie! Sony just gave the world a look at its upcoming Xperia Z4 Tablet in Xperia Lounge -- a move we'd assume was in error, since it quickly pulled the listing. It didn't give away the whole farm, however. Along with a sidelong pic (above) and reference to a high-res 2K screen (2,560 x 1,440 or so), other specs like "the latest ultra fast processor" were more vague. Sony added it would have "industry leading battery performance" and a "lightweight premium body," all of which bodes well for a high-end tablet. We still don't know key details like the size, but it might be a 10-inch model (unlike the 8-inch Xperia Z3 Compact), judging by the name and pic. You won't have to wait long to find out, as Sony also revealed that the tablet will arrive on March 3rd, smack in the middle of MWC 2015.
