The F-35 obviously needs more preparation so they're really going to do it first with Typhoons and those are cool and potent aircraft even if they're not completely "Made in the USA (TM)".
There's an internal BAE project to give them updatable computers which can be ripped out and replaced every few years. Like the Gripen the idea is to separate the flight critical software, which needs lots of certification, from everything else which can then be updated much more easily and rapidly.
They've also been flight testing a radar that can do electronic warfare as well as its normal job and the Typhoon, like the Gripen and Rafale carries the Meteor BVRAAM which is exceptionally good because it has a long range and a lot of energy to maneuver at the point where its nearing its target.
Some of the software is mission critical but not flight critical. If your targeting pod is down, it'll be harder to see the ground target or visually ID aircraft from afar, but there is no safety issue to the plane.
For example the aircraft is unstable by design and software keeps it responding and making changes N times a second (IIRC 40times/sec or something like that) without which it might crash - so that system would be one you don't want to change frequently.
