Spring has come and gone without any sign of Sony's promised X900C and X910C TVs, but those super-thin 4K sets are finally on their way... well, almost. The slimmest of the bunch, the 0.19-inch thick X900C series, is now slated to arrive in July at hefty prices of $2,499 for a 55-inch model, and $3,999 for its 65-inch counterpart. Determined to go bigger? You'll have to wait longer, and pay a pretty penny. The lone X910C model, a 75-incher, is poised to launch sometime this summer for $5,499. Thankfully, screen size is the only major difference here. All of these units pack Android TV, Triluminos displays and an X1 processor that should make the most of your 4K video. The real question is whether or not you need this eye-catching design in the first place -- it's great if you're aiming for a near-invisible wall mount, but you might otherwise be fine 'settling' for a thicker TV.
