Well, I read most of both those articles, and I don't believe either of them. In fact, I haven't believed one word about the Rev that has sprung forth from anybody but Reggie, Iwata, Miyamoto, or whomever can actually be proven to work at nintendo. While some of this may and up being true, we're all better off just not believing it.
The first one, from Nintendo.com, is bull. Why would someone who's leaking this info reveal where they work? Why would someone at Factor 5 know about SSB? There were other loopholes and fallacies in there, but I forgot them when I read the second article, the blog one that nemo posted the link to.
It seems that whoever wrote this took all of the complaints about other fake leaks and made excuses for them; I don't speak english, I can't be bothered to use puncuation, I'm pressed for time so I'll be vague, etc. There were some lines in there that seemed just....amature-ish, or something. Also, his name, Gemini.....hmmm, does that name relate to "Aries" in any way? Wait, aren't they both signs in the zodiac? * Also, it seems that whenever a new piece of "leaked" info comes out, there are a few other "sources" with that same new info that just showed up. When did the post at nintendo.com show up?
They both seem to build off of other rumors, except that second one was done much better. In terms of the technology both of them described, it all seems to be a bunch of gobbledy-gook, but I leave the rest of that to the more tech oriented forumers (feel the pain anywhere in your body? Seems...ehh...)
*The time frame that Aries showed up and the time frame of this here Gemini roughly match their astrological counterparts, however both of them seem to be a sign early. Just thought I'd point that out
