Real nice find !

It's called stealth marketing :)= a concept developed by
IBM marketing, which by the looks of it consists of former
Homeland Security People.

Well there are some nice info in that presentation as I see it:

POWER6 based p595 will likely be a 4TB RAM machine.(slide 7)
which isn't a surprise really, but will still only be a
64 core machine.

No POWER6 based QCM modules right now (slide 10), which I
think is a big big big mistake.

A POWER6 blade to replace the JS2[01],(slide 12) about time IMHO
that they got a real POWER blade.

p505,p510,p520,p550,p560 are history and replaced by a 4
socket p550, and the js2X POWER6 based blade, also a huge
gamble IMHO. I can see the logic in it because blade servers
are eating up the rack server marked from below. But still....

p575 will go from 16 cores to 32 cores in 2U that'll prob be
something like 900 in specintrate and 1k in fp.

Otherwise it's slide 14 that have the key points.

Partition mobility looks like something that could be
really useful in the datacenter together with partition

Virtual Memory sounds a bid like trouble.

And the Aix 6.1 Workload partitions sounds like a version of
Solaris containers, but with the added feature of you being
able to move your workloads between physical servers.

The Cell Broadband Engine™ Update by Michael Hennecke
have some really nice slides on roadmaps and the future
regarding the SDK and the actual hardware.
