Has anyone saying Munna -> Musharna -> Drowzee -> Hypno realized that Drowzee has awful stats? It means that Munna (and maybe Musharna) would most likely have even worse stats than SUNKERN. Even if it went Munna -> Drowzee or Musharna, that'd make Musharna pretty useless in-battle unless it evolved again... and if Hypno is any indication, Musharna 2.0 wouldn't be particularly good either.
I know that they can and will make sub-par Pokemon every generation, but given their efforts to make the early Pokemon more powerful (Staraptor and Luxray, for example. Even Bibarel has some amazing abilities), I like to think they wouldn't show us a weak, useless pre-evo without explicitly stating that it is one. Come to think of it, have they ever revealed a pre-evo without saying it is one? Or a new evolution for that matter (like Electivire and Roserade)? I only paid attention to 4th gen pre-release stuff, so I'm not sure.
Edit: Oh, and I loooooooove the new eagle guy. I went through a phase a few years back where I was just in love with birds of all kinds. While I got over it, I still have tons of respect and admiration for them, so yeah, I'm very pleased. I just kinda wish it were Fighting/Flying, since that's the only type Flying hasn't been paired with, and it could totally work for this one.
