  • Possibility of IBM to form an OpenPOWER consortium with key vendors like google, Nvidia, Mellanox etc.,
  • Heard IBM stating that no further increase in processor clock speed in new processor - however, rumors out there on improved clock speed.
  • Official release of POWER8 - date unknown/undisclosed
