Intel planning three new Thunderbolt controllers for 2012

At IDF earlier this month Intel revealed its upcoming Cactus Ridge Thunderbolt controllers, but it turns out the company is about to launch a third Thunderbolt controller and it should arrive ahead of Cactus Ridge. The yet unannounced chip is known as Port Ridge or L2210 and it's a low-cost device only controller which should hopefully make it more appealing for peripheral manufacturers to create Thunderbolt devices.
