That article did not state anything about there being cuts from the Brawl roster, just that not every character from the previous games will return. This extends to Melee veterans as well, so he could just be saying that he doesn't have the resource to bring back characters like Young Link and Pichu back to the initial roster (though that's not to say Pichu couldn't appear as DLC). Also compare the attitude from cuts he had during pre-Brawl and compare them to now. Take a look at SamuraiPanda's translation
all the way back in 2006:Sakurai said straight up that characters from the last game were disappearing. He doesn't really stress on trying to keep as many characters in from the roster as possible but promised that those who would make it would be remade.
Compare that to his attitude towards cuts he's shown so far. Note that not only has he not confirmed cuts from Brawl, but also thinks a lot more about the fans. He realize just how much it hurts to see characters axed and stresses about trying to get as many characters in as he can. Already, he's showing much less willingness to axe characters and has publicly apologize beforehand for cuts should they happen.
It is for this reason why I consider anymore than three cuts to be very unlikely and that I definitely do not see more than four. The only cuts I see happening for reasons other than time constraints are Snake, Sonic and Toon Link (and even then, I have doubts about the latter two being axed). If Lucario and Ike were to be cut, it would be due to time constraints and only time constraints and should DLC happen, they'll be brought back anyway.Nintendo has been more open to DLC recently. See the release of New Super Luigi U, which is DLC for New Super Mario Bros. U. They like the concept of DLC, but not DLC that are developed beforehand (like on-disc DLC Capcom has used on many occasions).
Sakurai has also commented about
not being opposed to DLCs and liking DLCs like Fallout 3. While he has definitely not confirmed DLC, he hasn't ruled them out yet after the game release. He'll likely use DLC to finish up characters he wants to see along with other planned but unfinished ideas should he use them. I'd say the chances of DLC occurring are 50/50; depends on if Sakurai has anything major he wanted to add but couldn't due to time constraints (characters, stages, etc).There has been a trajectory of clones becoming more unique with each game. Brawl "clones" were more unique that Melee clones. The only Brawl "clone" that could be argued as one is Toon Link and even then his play style stands out more than Young Link did in Melee and he looks more differently. SSB4's "clones" will probably be even more unique than the ones from Brawl. If Roy returned, I'd expect him to be at least as unique as Falco and I wouldn't be surprised if he hit around if not above Wolf's level of uniqueness.
Also, Chrom/Lucina is not going to bring a new audience to Smash. Most people who play Fire Emblem play Smash anyway and it's not like people are going to be running out to buy Smash for one of these two.
