Q3 is set to see Intel introduce its P55 chipset and Lynnfield C2Q CPUs, but apparently they also plan to add new features to the X57 platforms in Q1 2010.
P55 will support Intel storage matrix 8.5 with Raid 0,1, 5 and 10 featuring Intel rapid recover technology from Q3 2009 launch, but the rest of the listed features will become available in Q1 2010.
