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.

Block 4 Upgrades Prompt Rise in F-35 Program Cost
02 Aug 2019 John A. Tirpak

"The total cost of the F-35 program grew by $25 billion in 2018—or about $95 billion when adjusting for inflation—in part because of a new slate of upgrades known as Block 4, the Pentagon said in an annual acquisition report published Aug. 1.

Acquisition alone—including research and development, procurement, and military construction costs—rose by $15.3 billion compared to the 2012 baseline, or $22.2 billion when adjusted for inflation.

The Pentagon also noted a dispute between its cost assessment and program evaluation shop, which believes Joint Strike Fighter operations and sustainment costs are rising, and the F-35 Joint Program Office, which argues those costs are shrinking.

Lifetime costs for the entire fleet of US-operated F-35s span design and development, purchase of the jets, repairs, spare parts, modifications, upgrades, operations, military construction, and inflation over a 53-year period.

...Overall development costs, which rose by $10.5 billion compared to the 2012 baseline, include the price of Block 4, designing F-35s to carry nuclear weapons, the growing costs of the Autonomic Logistics Information System, and higher expenses associated with deployability. When adjusted for inflation, development costs grew $12.4 billion.

Production costs went up, too. The most basic F-35 cost metric, known as the unit recurring flyaway cost that covers the aircraft and engine, rose by $2.1 million per airplane for the F-35A, $2.8 million for F-35B, and $900,000 for the C model. Those numbers reflect costs incurred during production prior to the ongoing Lot 11, the Pentagon said, after which the unit price is expected to plummet….

...The CAPE office estimates that operations and sustainment grew by $9.7 billion (or $12 billion when including inflation), but the JPO said O&S decreased by $23.1 billion (or $8.5 billion when including inflation).

The program office’s O&S estimate dropped by nearly 4 percent from fiscal 2017 to 2018, following guidance from the Office of the Secretary of Defense....

...Cost per flying hour dropped 2.3 percent for the F-35A, 1.8 percent for the F-35B, and 5.3 percent for the F-35C—the most up-to-date aircraft in US service. F-35A and F-35B costs dropped based on OSD guidance, while the F-35C’s cost per flying hour fell from changes to the propulsion cost estimate.""
