So glad I have Tasslehoff's Pouches of Everything from the Nexus!It seems to me that WotC's current approach to lore, even in their setting books, is extremely detail-light, very restriction-averse, and also very have-it-both-ways.
So while they certainly would never say, for example, "There are no orcs native to Krynn," they also probably wouldn't add orcs to the setting explicitly. They're more likely just to not talk about orcs at all, so that those who don't know about or don't like orcs' absence from the older Dragonlance lore will just assume orcs exist there (just as, say, gelatinous cubes would be assumed to exist even if the guide doesn't say so), and old-school fans will feel free to exclude them. (This applies generally but is doubly likely in the specific case of orcs, which I imagine WotC probably aren't too keen to foreground at the moment.)
On the other hand, I expect certain elements (e.g., gully dwarves) to be severely retconned. Actually I do expect a full-on timeline reboot to the War of the Lance era, but I also figure the facelift is likely to be limited mostly to sensitivity changes.
