Spoilers/Speculations for final episode

I've read quite a bit of spoiler info and seen the Canadian Global Promo on Youtube, to make a few speculations..they may or may not come to fruition, don't read if you want the show to possibly surprise you..

The money would be on Sylar escaping (obvious, we need him as the villain), and he will turn Eden's powers on her. Sylar already turned a gun on Matt the cop's partner, so he will turn a gun on Eden in this final episode of the year. Surprising, since I read that Eden would be a love interest still for Mohinder..

Now another possibility is Sylar is the one who "gets killed". Maybe its just to shock us and make us think "well maybe he's dead". That would be one interesting twist.

The Canadian Global promo shows the Haitian with his hand over Claire's mouth asking her "can you keep a secret?". So it looks like the Haitian may turn against HRG, and kidnap HRG's family.

Next we have some heroe's meeting up. The promo shows Matt with DL, Micah and Nikki, somewhere, and Peter as well. So let's speculate they are all either in TX or Los Angeles. Also, Hiro will be going to NYC to meet Isaac. Another speculation; Isaac is returning from HRG's care and possibly mentoring. Isaac just might be a traitor.

I've read spoilers saying Peter goes into a coma, possibly he inherits Ted Exploding Man's powers and it forces him into one. Would be an interesting twist.

So we might start to see a division occuring; heroes and villains. The good guys vs the bad, with the bad team of Haitian, Sylar, Ted and maybe Isaac or HRG. Gonna be another great episode of Heroes..
