My hope would be that they stick with 5e. Level Up did after allSome companies create products with different versions for different game systems. It's not uncommon for RPG books to have a "5E" version and an "OSR" version. Free League offers a 5E version of each title in the "One Ring" product line. I've seen "D&D" and "not-D&D" versions of other games in the past also . . .
But yeah, expecting a companies to publish "5E" and a "6E" versions as the norm . . . other than the OSR stuff, that hasn't really happened on any sort of scale ever. Nor would it currently.
