Actually, I don't believe the level cap will be ten, I think it'll be twenty like the core rules. Maybe they're presently working on all the content for levels 1-10, for early access you know. Given the purported length of the game, and the relatively fast leveling in 5e, ten levels doesn't make much sense. Unless, of course, they plan to use milestone leveling, though one notices XP being handed out in the demo for combat.
I think they were pretty clear that the cap is 10 for full release, not early access.
Can you say anything about the level cap?
NickP: We’re planning to cover levels 1 through 10 in full release.
