Star Trek The Next Generation Sequel: 10 Things It Must Have
6. Picard The Explorer
As already qualified, Picard needs to be in some way tied to a new Enterprise in the new show. But that's only part of the story - he also needs to not be "commanding" a desk at Starfleet when he returns.
There have been rumours that a Picard show would focus on him training at Starfleet, but that's akin to putting a lion in a cage. Sure, it looks like a lion and it might still roar like a lion, but it's nothing like watching it prowl the open planes looking for prey to hunt or standing atop Pride Rock singing majestically. Wait no, wrong metaphor.
Anyway, a Picard who isn't boldly going anywhere is only half of a Picard, and while it might make sense for his age that he'd not be on active duty as a captain, it would be a major shame if he wasn't in command of his own ship and still pushing the boundaries of exploration. Nobody wants stagnation, no matter how old he is.
