I can understand the sentiment here, especially when the Exposure indices
are not especially high. but when we start talking about ISOs of 50K and
greater on high MP cameras, we're not talking about somethiong where large
images are expected. Web-sized images, for journalistic purposes and small
prints, are what we are using these super-high-ISO shots for, in general.

Here's my 7D at ISO 3200, under-exposed 4 stops, for ISO 50K:

You can't do that with a 10D, even a 5D (without banding). You can't do
that with any Olympus or Pentax. You can't do that with the older Nikons,
like the D200 or D2X.

So, I would say there is some value in showing small images - *IF* it
actually means something.

OK, Rich, I CALL. Please post all the details of your 'test'.

After all, this goes to the core of your credibility here...

I *do* hope it was done correctly and scientifically.
