More info about Destiny

So I finally got a chance to read all the new things about Destiny and I cannot wait I love cinematic story's I mostly PvE and I keep debating and debating on which class to choose on launch between Titan and Warlock. They both look pretty awesome but which one will be better I'm conflicted still looking forward to playing with fellow grimguardians. Gonna start sitting up my fireteam and what not so if anyone is interested in that let me know.
