Ypu should expect Pioneer's second generation of BD burners this summer, mainly offering 4x for BD-R and support for LTE media (organic layer). A hybrid BD/HD DVD drive will be also available in September.
Samsung also plans a hybrid drive in July.
Don't expect many changes this year, such as higher recording speeeds etc. The Blu-ray disc association is focusing on the BD-ROM segment. They still facing problems with the Blu-ray licensing procedures as well as with the AACS licensing, which has not yet been completed.
