Is one coming?
I think one of the biggest missing items in Canon's lineup is a useful small flash for the likes of the G10 and SX10IS. There aren't too many people that will spend about the same amount of money on a flash as they did the camera.
I was told last year that a new 2xx series flash was coming. I have nothing concrete that it'll be introduced at PMA, but hold tight.
I'll add easy linkage to the top of the site shortly, my internet is a bit wiggy this week.
