10MP aside, I would not expect you to see anything remarkably different to the camera you already own?
Is this the sales department talking?
The 60 has APL and
much better auto-focus
( but I should be able to get good auto-focus using the extra focus light on my Metz flashes)
...but one thing thay I look forward to is being able to
fill the width of a 24" (7900) printer @ 360ppi
or to print 24 * 36" @240ppi
or, with a single row stitching back, print 24" * whatever
without scaling or up-rezing.
Fortunately I have the option to upgrade without spending a fortune.
I think the the upgrade from phocus to phocus 2 make more difference than the extra 10 Mpx. but I have that already.
