Corsair is working on its big blue version of Voyager memory stick. A blue variant of stick will double its capacity from 16 to 32 GB.
It won't be the fastest thing on market but it will be one of the largest for sure. It wont be cheap either probably more than $ / €250 but you will be able to store a lot on it.
Corsair also officially announced Voyager GT also known as the red one. The biggest capacity is 8GB but this one is much faster than the blue one, at least it should be.
This one should be out in April.
