You really can't say any of this stuff is spoilers until to movie comes out to prove or disprove them. Everything reported here are potential spoilers.
As far as Han/HF goes, yes Harrison wanted Solo to die after ESB because he felt the character had nowhere else to go. But that's precisely why I don't think Solo will die in TFA...because given HF's past oral history about the character, it would be far too predictable to kill him off now, at least in the first movie. I'm predicting that he will live through TFA to fight another day and be killed off in ep 8.
We'll find out either way in almost exactly 4 months. I can't believe it's almost here after all this waiting, but I can't wait either.
Actually you can, as the same sources provided rumors which became manifest as spoilers from the 2 trailers and BTS footage. Months before anyone saw those images, they were described exactly on these web sites. So since their veracity has proven true, why would they suddenly get everything wrong? They have gotten some wrong, but nothing really major. And no one yet knows the true lineage of Rey, Finn, and even though it's looking like 95% certain, Kylo. And Snoke, forget it, not one good bit of rumor. So this isn't people throwing stuff up hoping it sticks.
