We don't actually know if Pikachu is the only 'mon you can play as, although it seems extremely unlikely, or how many different 'mons will be available for heroes/partners. They probably are waiting to reveal the entire roster. Remember, the game was only announced recently and we haven't even gotten translations of the first scans yet.
That's what I'm waiting for. If we could get these translations and at least get some idea of knowing what is to be expected, then I'll be more than willing to know more. What irritated me was seeing you (as the main character) turning into a Pikachu. I was assuming you'd stay as a Pikachu, wheras in the original dungeon games you could be anything. Since it is a standalone, I conclude that Pikachu was the only character you'd be in there gaming, having no relation or intent in being
exactly like PMD: Blue, Red, Time, Darkness, etc.

Since it's not confirmed, I don't think Pikachu's our only option. They're probably not that jerkish. Also, you can see images that show you turning into a different pokémon.
Like above, more dialogue for the recruits would be awesome. I also would like the idea of not degrading your partner to a generic 'mon like in Rescue Team, yet let you be another pokémon in the overworld, unlike Explorers. Playing as the legendary Zapdos while walking through a town was pretty funny.
The images that show you different pokemon could be the partner selection, like in the other PMD games where you go down a list of pokemon, showing their mugshots. Other than that, I'm slightly convinced after taking a second look.
Heh, and having a massive Palkia/Dialga walking around with you in Sky, Darkness, and Time seemed impossible, but they managed to squeeze their sprites in such a confined environment.
