So something suspected for a while but no official confirmation, the Radar is also updated

I think the radar improvements are the new & improved modes that have already been announced.

I know a new panoramic display is coming in Block 4, but are widgets (graphics, icons, etc.) on the display going to change, be updated?

Unlikely; that'd mean having pilots re-train on the system for little reason.

Then why the new display? To take advantage of increased resolution of the EOTS, etc?

Why new displays? Obsolescence, DMS (diminishing manufacturing sources), R&M...could be any or all. TR3 stuff.

OVER on the PCD thread (where ever) there is old talk from Head Designer of PVI Pilot Vehickle Interface (I feel I can spell Vehicle that way because some clowns spell LIGHTENING) says there was/is a plan for colour icons but a standard had not been devised at the time of statement (because NEW). Also there was some hope for more game like 3D display in future.

"...having pilots re-train on the system..." pilot bread & butter to retrain IF it is worth it and because they are worth it.

Over on another BLOCK 4 thread 'SWP' has a guess: viewtopic.php?f=62&t=27390&p=404492&hilit=color#p404492

COLOUR/color in HMDS: viewtopic.php?f=62&t=16223&p=404868&hilit=color#p404868

Besides what quicksilver said, there's also the resolution increases coming to the EOTS and DAS which will require higher resolution displays to view properly (you can't get the full quality of a (eg) 2k x 2k sensor if your display only has a 1280x1024 resolution; not without zooming in and decreasing situational awareness). The heat generated by the PCDs has also been noted in the past and these new displays have a threshold requirement of consuming 2x less power (objective 4x less), which will assist with that.
