Good post Joe and I would add that Anne might be burying the wrong thing (although I don't see anything on her list that won't evenutally dominate the IT scene).
She's mixing up the buzzwords as if they all were like things, But:
BPM is a value proposition; been around 100 years or more (see http://www.ebizq.net/blogs/bpminaction/2009/01/bpm_viewpoint_so_where_does_th.php.)
SaaS is an IT delivery method; been around for 50 years
Cloud computing is a way to configure IT infrastructre (I prefer "timesharing system" which has also been around for 50 years)
Mashups is portal integration; been around for 10 years
SOA is just what it says it is, an architecture; been around for 20 years
Almost all packaged application software will be written to SOA principles by about 2025 (just as the switch from monolithic to C/S that began in 1990 was complete by about 2005).
Once all pacakged applications are re-architected to SOA, the rest of IT will fall into place.
