I think Lapras definitely needs something. I would go pre-evolution, because it is pretty good on its own now. A pre-evolution for Miltank and Tauros would be nice too. ^^
As for evolutions, I think Corsola could use one, and I think Pinsir could use one. I guess one for Jynx would be alright (after all, Magmar and Electabuzz got one), but not necessary IMO. They'll probably pull something unexpected on us too, like a Gallade or a Rhyperior.
I think Smeargle could evolve having an ability that works like Trace, but keeps it permanentely like Sketch. Or it uses that opponent's ability until the end of the next battle.
Making the stats just 5 base stats higher, excluding speed (to make it less broken obviously).
...then they should put wild Kyogre or Groundon to mimic their awesome ability =D
Or this could be a new attack this Smeargle evo learns.
Luvdisc is the most stupid Pokémon and definately needs an evolution.
I would like to see a
Relicanth evo *drools*
but he doesn't need one.
Pinsir NEEDS one, and I'd
like to see a better scyther
evo. It would be cool to
see an Aerodactyl evo.
He's the only fossil without one.
