They got that from Intel:
Nehalem-EX will add new reliability, availability and serviceability (RAS)
features traditionally found in the company's Intel® Itanium processor family,
such as Machine Check Architecture (MCA) Recovery.

It's true that the mca flag has been present on previous generations
(Harpertown and Clovertown at least). I don't know how complete the
implementation was, and what the real improvement (if any) is on Nehalem-EX,

2010 is not so far away anymore, and Nehalem-EX will probably be there before
Tukwila anyways. It feels like this announcement is a way for Intel to make
the Itanium branch less and less appealing.
IIRC what our SGI sales rep told us, SGI will be working on a x86 version of
NUMAlink for their Altix series, using Nehalem-EXs instead of Itanium2s. So
customers in the SMP market whose only choice was Itanium will probably turn
away from it to adopt the x86 line.

That's a marketing trick: let people wait while distilling such announcements
so the "me want" factor can build up. :)
