Supernatural Season 5 - Series Ender?

After what seems to be an eternity, I finally completed my Supernatural Season 4 download on uTorrent. I have been aching to watch this latest season after being cliff-hanged on Season 3.

Where we last left off on season 3, Dean dies in the hands or paws rather of the hellhounds after his deal has reached its deadline while dealing with Lilith in Ruby's body.

I am still watching the 4th season, and time would stand still again if I finish the season. But wait, there were rumors spread around that the 5th season would be the last for the Winchester brothers. And Eric Kripke, creator of Supernatural, confirmed this.

Eric Kripke had said that they had a 5 year plan for the Winchester brothers, (Jared Padalecki and Jensen Ackles), and they had worked them both so hard over the year. And now, the saying goes, all good things must come to an end.

Who knows what's in store for the Winchester should the 5th season start? It's tad disappointing to know that one of the best TV series is coming to a complete end...
