xD card is fine as it is either xD or SD for small digicams and well, Olympus are stuck with it I guess.
Reading throught the review, it does look like a very attractive camera to me and looks like it will be very quick too in terms of shutter lag. I like that they still retain the viewfinder... don't like all the recent digicams that have no viewfinder, so difficult to use in strong sunlight no matter how good the LCD is.
And that grip is very nice for such a camera, I will never buy a camera without a proper grip and looks like this camera is class leading in this respect too.
It is plasticky alright but based on Olympus track record, I will expect the plastic to be solid and nice to the touch and not 'hollow' in feel.
Hope the noise levels in the new 8MP CCD is on par with that of the C7070WZ and C70 and they will have a winner.
