Intel have reportedly notified their partners that they will "fully release" Thunderbolt technology in April of next year. Intel are said to be preparing to launch Thunderbolt-supported motherboards, notebooks and desktop PCs at that time.
Intel and Apple originally partnered on Thunderbolt which became a standard across Apple's MacBook Pro, MacBook Air, Mac mini and iMac lines. The cost of Thunderbolt technology is said to drop in the second half of 2012, which will allow for much more market penetration.
Apple may offer Thunderbolt-equipped goods, but the first Thunderbolt products have been limited to the relatively high-end market. Widespread adoption of Thunderbolt should help accessory makers for not just the PC, but the Mac market. Intel have always said that they see USB 3.0 and Thunderbolt as complementary technologies and have plans to support both in their motherboards in 2012.
