Items missing is expected because you have to buy them in the shop.I'd just point as important reminder that they played a dev version with incomplete availability of items / pokemon, with a extremely forced experience and no chance to "experiment".
Most of the missing features (some moves not having full data, pokemon and items missing) are likely to just be there on actual release.
Pokemon missing is a native feature of the game having a limited roster.
Move descriptions being incorrect is something that I fully expect to carry over if the game releases in 2 weeks and they feel comfortable showing this as a selling point, I doubt that's still being tweaked last minute.
