It was way back in September that the leaves fell and revealed Intel's plans for the Cactus Ridge revision of Thunderbolt chips. Now, VR-Zone claims it's received confirmation that the second generation controllers are finally shipping. As already announced, there are two versions: the quad-channel dual DisplayPort DSL3510 edition, and the double channeled Eagle Ridge replacement model DSL3310. It would be careless to speculate about which OEMs might adopt, and in what models, but with Apple already flying the Thunderbolt flag, that's at least one name you can scratch off the list.
