Glad to hear you're more into the later versions :D
As far as the gallery goes, the next patch will flesh it out significantly, adding in every animation in the game, being able to see the cutscene where the NPC/boss/etc. scene took place, endings, and so on. (It won't have the variants for the bosses though, just because those would be a bit of a nightmare to setup).
We'll keep going though until everything's voiced and fully in for sure!
