Gaming is fun, and fun is for everyone
That basically what I meant by updated, the current information you need to run games in a place at the current year in FR, aka current events and what that place like now (cities, current events/plot hooks, laws, rules, etc...).
The expanded part is clearly WotC wants to add some new stuff to the setting like the new Drow cities.
I really care little about the timeline. It's never mattered before; Durnan and Mirt still being alive and looking the same is handwaved away with "longevity potions." So I really don't care what has happened in the 20 year gap (or whatever length of time it is) since these regions have been covered.
What I do want is pitches on what makes each region/country unique, and what type of adventures are well-suited there. So for example, Cormyr is a place I'd like to know some lore about their society and why chivalrous nobility is important. Then, pitch me a few ideas for what adventures are great there.
The timeline of FR is a complete mess in 5E, and I don't care enough to see it fixed. What the exact year is clearly doesn't matter to the 5E designers, and it doesn't matter to me. Keep the fundamentals of these locations the same, and make this a toolbox to run games in. Please don't bore me with "In the last year, this prince bumped off the Queen and set off these reforms..."
