Joshcryer is a Capriles supporter (rightwing) and very anti-Chavez, so I don't credit his "time of sadness" prediction and I suspect typical rightwing surreality (a super-reality wherein those who believe that they are "born to rule" wish themselves into power).
The method of Chavez's arrival in Venezuela--quiet, no fanfare--may be merely a reflection of his desire for privacy about his illness and treatment, which he has manifested all along.
Also, the fact that he's traveled home points to improved health, although it could be that he beat the post-operation lung infection but still has cancer. But if he still has cancer, why isn't he still being treated for it in Cuba (one of the best medical systems in the world)? If his cancer has spread and they think he's terminal, that might be a reason to discontinue aggressive treatment and let him travel home, but why assume this? There is little basis on which to assume it, and there are contraindications--he beat the lung infection (a complication that should have done him in, if his cancer had spread), is not intubated any more (according to the photos), has not lost any weight (according to the photos--quite surprising, considering what he's been through) and has become well enough to travel by air (not recommended for critically ill patients, especially recently intubated ones).
