That may happen (I explicitely allow this to happen) until there's more variety of things.
Not really right now. I might add a video for this update showing examples of new guns (using just a few different weapon parts).
I find it better to release stuff earlier, as soon as it might be shown, to get feedback. This way I may modify it sooner. If I'd be holding up, I could have either something worse or much more to modify later.
Downside is that despite the game marked as still in the development, some peoplemay expect this is the final version.
