AnandTech heard from sources at motherboard makers that Intel's X48 and P45 are both delayed. The X48 has been delayed to early to mid-March while the P45 is slated for June and the G45 sometime this summer:
According to several motherboard manufacturers, it now appears that final X48 silicon will not reach the suppliers until early to mid-March. All indications are that X48 products will not be in the retail market until the later part of March now. This is an abrupt change from the expected release of retail product later this month. However, considering the number of dates we have been given on this program, it's not surprising we have yet another schedule change. In their defense, Intel has just said Q1 as of late, but we know from Internal documents that Q1 originally meant January. Oh well, it gives us a little more time to play with NVIDIA's upcoming 790i besides reporting on some interesting P35 and X38 boards coming to market at the lower end of the price scale.

Our sources tell us not to expect the next generation mid-range chipsets from Intel until the "Computex" time frame now with variations of the chipset like the G45 possibly coming a little later in the summer. We originally expected an early Q2 time period based off previous discussions but it appears to be late Q2 for product announcements now and shipment of the P45.
