"... stuff like DDR3 and QPI..."
Ha ha ha!!! Nice Matt. You're right, those are great advances... LOL. and when will they be released? You don't know, do you? There have been regular Niagara and SPARC64 at least every 6 months. When was the last Itanium update????
Montecito came out in 2007 (2 years late) and just added dual cores... Montvale came out in 2007 and only added more cache. Two years and still no new chip! Where's Tukwila? Intel has been promising Tukwila since 2003, of course they called it Tanglewood then. Intel first said 2007, then they said 2008, then 2009, and now 2010!!!
Don't believe me...

Heck, with Intel's 3 year old chips both Sun and IBM can beat the snot out of Itanium.
Sure there are a couple of cherry picked benchmarks that HP does well on, but when
you actually run your application on the systems you see a massive performance advantage
for both IBM and Sun. Itanium is behind and if they don't start releasing chips more often than
every couple of years, then they will fall further behind. No frequency advances, no core advances, no thread advances, and their bus is sorely behind... QPI better be as good as they say, 'cuz they're hurting if not.
I was looking forward to ROCK, but SPARC64 screams at the high-end and Niagara is quickly moving up the performance/scalability ramp. You can actually see the advances of Niagara on a regular basis, while Itanium is a snail in comparison. Is Intel actually investing in Itanium anymore?
