I'm getting the impression you think PM is just Brawl that plays like Melee plus skins. They have added more than just skins,It's not just them. There's a lot of other Modders who can do stuff too. Sure, they're specifically working on Project M, but most other Modders don't bother to do much at all. Keep in mind I am not expecting original characters for a long time, if ever. But more than just skins would be great, and I don't mean for Project M, but in general. I don't find skins all that impressive on their own.
But is nice they might add ones like Lyn into the game. Much like Shadow was done ages ago, and a fairly bad version of Waluigi(it had great ideas and had a neat moveset, but it was glitchy).
I mean turbo mode is completely new too. Whose to say they can''t create new modes as well; along with possibly new characters?
I'm not even that big of a PM junkie (Actually I'm playing it now for practically the first time (I wanted to wait for Yoshi)), But I think there is potential in PM mod.
But to be perfectly honest, ill probably drop the mod in a heart beat once SSB4 comes out.
All I am gonna say is be patient and see what they do moving on.
