Hi Ian,
you must be having very busy days with PMA in just two weeks.
Well, it's my pleasure. The launch date has IMHO little meaning in the real world. A good example is Pentax K10D. I watch and touched it for the first time last week in Tokyo and now I believe its existence. And to my surprise I found it in my city too today. So for this city, today is the launch date.

IIRC it seems it was introduced first in Australia in Oct and then in some other larger cities in the world. I now learned it takes nearly three months until a new one comes to my city.
Many manufacturers see higher growth ratio of DSLR in especially Europe, so it is no wonder that Canon introduce it first in Europe. We already have an example of Olympus E-400. Have you already heard anything about the three models coming shortly?

Or is it a too touchy question at this right moment?
