Not to mention the state of the art hasn't moved very much - that 27" IPS LCD panel is still the very same that's being used by Dell, HP, et al.

There's been a lot of development on both smaller and larger screen sizes, but the 27" form factor seems to be at a relative standstill.

I don't expect to see an update unless there is a major change to either the panel tech or the interface tech. I really do hope that Apple reopens the >= 30-inch space though.
