No no, this time we MEAN it.  For reallys.  The X48 chipset is coming in mid-March, according to Intel according to Digitimes.

Intel has informed motherboard makers that it will definitely launch its X48 chipset in mid March, two months later than its original launch date, according to industry sources. The X48 chipset was originally slated for launch in January, but Intel pushed it back as inventory of X38 had yet to be cleared, the sources said.

Some makers, such as Gigabyte Technology and Micro-Star International (MSI), have already announced details of their X48 motherboards, but Intel’s delay in officially launching the new chipset is preventing the mobo makers from setting shipping schedules of their new motherboards.

But Intel has told motherboard makers that the mid March launch date is definite, and there will be no more delays, the sources claimed. As X48 will be launched in mid March, the Core 2 Extreme QX9770 that the chipset supports will not be available until then, the sources said.
