I'm sure none of you know me, I used to hang out on the Brawl boards before release all the time. I never really posted much though, just followed the dojo hype train with everyone else around that time. Anyone that was around then knows there were legitimate leaks, but no one believed them at the time because of how crazy they seemed(wtf ROB?). Well there was a user in particular who leaked correct information that I managed to befriend around that time, this person is no longer active on gamefaqs, nor do they have plans to return.
I didn't befriend them right away, it took a bit of work, but it eventually got to a point where we would talk every now and then over AIM or Skype. I was mostly interested in their line of work, as at the time was aspiring to work in the video game business. After awhile we kinda fell out of touch, but I saw them on Skype today and figured I'd say hello and see if I could find any information out because I've noticed all these "leaks" lately around here and people going back and forth about them.
My friend wasn't particularly interested in sharing any information with gamefaqs, and told me gamefaqs wouldn't believe anything anyway. I agreed and asked if they would just answer a few questions at least, and this is what I gathered:
Ridley is not playable, he's a stage hazard.
King K. Rool is not playable.
Diddy is not partnered with Dixie.
Online will have way more options then Brawl, like being able to host rooms with your own item/rule set ups.
That's all the info I was able to get, I couldn't squeeze one new comer out sorry. I tried to get a Little Mac confirmation at least, but they wouldn't confirm or deny. Obviously I don't know if this information is legit, I could have been lied to very easily. My friend wasn't treated very well by the Brawl board users, and I wouldn't be surprised at all if they were just yanking my chain. This the first conversation I've had with them in like 2 years so take that for what it's worth.
