This is a RUMOR, folks. I can't emphasize how much of a RUMOR this RUMOR is. So please don't think of this RUMOR as anything but a RUMOR. Now that that's done with, MILOX4 on the Nsider forums has posted something very intriguing. Take a look at what he said:
So, my friend finally received his subscription magazine today (Laaaate, it was supposed to arrive 3 days ago). And wow! apparently, Club Ventendo (Mexico D.F only) got an interview with Sakurai himself, they talked mostly about old stuff and Smash dojo, but they also talked about Sonic and then... Big secret! apparently, Sonic is already in the game, according to this magazine, SEGA only needs to give a final confirmation to put him in the game (They already said "yes", but apparently, some problems surged recently before the E3 and they told Sora to hold on and wait for a final confirmation). The magazine says we will get an update about Sonic this month, on July 26th, confirming if he will make it in the game or not.
Sorry, I the magazines page is down right now, but I took a photo of the page, if you can read Spanish, give it a try.
Anyway, here's the link to the photo:
One last note: That magazine has NEVER given false info, they take pride on always giving info 100% confirmed by them.
What picture is he referring to? This one:
Do I think it's real? No, for two big reasons:
1. Sakurai wouldn't give away if Sonic was in Brawl or not to a magazine that pretty much no one has heard of. It would be on the site first.
2. MILOX4 posted this on the 19th, and claimed that he was supposed to get it 3 days before, which would be the 16th. On the 19th, Sakurai updated the Smash Bros. site with some Zero Suit Samus stuff. That picture of ZSS in the magazine.... we didn't get that until the 19th. So, how could this magazine have it ahead of time?
It looks fake to me, but I'm posting it just in case. Take this with a huge grain of salt.
UPDATE: We know have a translation thanks to BRAWLBOY33 on the NSider forums:
"C Doriga: The time is running out, 1 last Q?
Will u include Segas mascot, Sonic the hedgehog?
M Sakurai: Well...this is a hard question, sonic is already in the game, but we still need segas last confirmation, due to the relaise date, Segas confirmation last day is 26th this month, on this date an update about sonic being in or out the game on the official site is planned, personally im crossing my fingers"
I'd still take this with a huge grain of salt if I were you.
