Up until now, Thunderbolt has been the preserve of Mac users with other manufacturers slow to pick up Intel's speedy new standard (models from Acer and Gigabyte, as well as the DisplayPort-defying VAIO Z, excepted). The hot plugging issue results from the way Windows handles the port, scanning for connected Thunderbolt devices as the OS boots up and then not monitoring for any new connections thereafter. AnandTech also found that there's a greater propensity for devices to hang on Windows, breaking the daisy-chain of devices linked after it — but we'll have to wait and see whether MSI will fix these issues by the time the board is released.
