Today it's a mid range consumer camera that has a decent video
feature. Tomorrow it might be a pro camera that instead of flapping
the mirror up and down for each frame allows you to keep the mirror
up for any selectable amount of time and shoot at frame rates that
are much higher. Casio's Ex-F1 shoots 60 fps at full res for a full
second, the new RED epic camera shoots at 100 fps using a 20 mp
sensor. The technology is there and we will see it being used by SLRs
soon.
The D90 is just the step.
It's funny and always the same pattern. Someone comes out with
something new and different, and many say, what the heck would that
be useful for. Then every manufacturer does it and then everyone
says, oh sure.
When the D300/D3 came out with their 920,000 pixel LCD many pointed
out how irrelevant that was and the LCD was not for high quality
viewing anyway, and all that blah blah. Now that the 50D will have
one (finally) it a feature worth pointing out.
