MJ has always been very cryptic. he likes playing and toying with the fans. It's FUN. MJ doesn't like being like every other artist that spills everything all at once. in fact, MJ's cryptic ways and mysteriousness is probably what got most of us intreged with MJ in the first place.
MJ doesn't wanna say NEW ALBUM specifically because it's probably not just a new album he's planning. I'm thinking it'll be a whole lot of stuff we can't even imagine up his sleeve. And he's also not saying it cuz he doesn't want TOO much buzz going around about it prematurely. It's all about timing. And MJ loves to play around with surprises. So peeps complaining about MJ not being upfront gots ta get over it cuz it's gonna be like that for a while. But its so much sweeter when the final product comes after such anticipation. Better than knowing everything and not being surprised by anything when it happens.
