There a lot of rumor sites out there, many posting unbacked speculation in hopes of getting attention from the Mac community. Unless they could cite a source or is a rumor site known to be credible (like MacRumors) I would not believe what they say.
One big thing I noticed is that MacOSRumors was cited as a source for one of the rumors. That site is not known for its credibility, and I would take anything they say with a grain of salt.
