Apple's OS X Mavericks hints at future Retina Thunderbolt Displays and iMacs

Amid Monday's excitement, it was discovered that the blue-and-green ocean wave wallpaper image Apple released to promote its upcoming OS X Mavericks for Mac is fitted precisely for a 27-inch Retina Thunderbolt Display, or even a 27-inch Retina iMac.

The 5,120-by-2,880-pixel image hosted on Apple's website is sized at exactly twice the width and height of the 2,560 by 1,440 pixels found in today's 27-inch iMac and 27-inch Apple Thunderbolt display. The Retina-caliber wallpaper was first noted on Twitter by Web designer Marvin Scharle.

Apple first hinted at Retina display support for its MacBook Pro lineup in 2011, when a developer preview of OS X Lion included a high-resolution wallpaper at 3,200 by 2,000 pixels. But Apple didn't release its first Retina display MacBook Pro until mid-2012, over a year later.
