In my opinion, fans are so very desperate nowadays that they will cling on to the slightest possibility of an MJ appearance/tour/performance/album etc. MJ and rumours go hand in hand, he is the subject of a lot of interest to many people for many different reasons, good and bad. What I feel fans need to use a lot more of is their own intuition and common sense and really just try to be unaffected by it. Until absolutely ANYTHING comes from Michael or his spokesman/people, then it can simply be classed as not true. I mean, what have we had so far this year, the grammys, some concerts dates at the O2 centre in London, which I admit to being sucked in by however nowadays, for me personally, I no longer have the time or energy for speculation, all that is second guessing and I know some people think its fun but realistically, no amount of it will make it happen all the quicker, if at all.
Whenever Michael is ready to make something happen, he WILL let us know about it in one way or another. Thats all you need to know.
