To all you sopranos fans!!! what was up with the final episode?It is still bothering me!?

Do you think Tony got wacked? it was strange how the show ended. wasn't what I expected. Very disapointing for a final episode. What was the whole significance of the Journey song, how it took his daughter so long to park her car, and I'm wondering if that guy that was sitting at the bar was a Fed. The ending was weird and unanswered.
