Is anyone else heartbroken that Heath Ledger won't be in the next Batman flick?

OMG mr markwill whatever! Heath's role as the joker did not lead to his death! Everyone knows that! IT was an ACCIDENTAL overdose. Gosh. ANyways I think they should stop the batman series cause NO movioe will evr top that one. none. ever. I mean the joker i s THE villian of all Batman's arch nemesis so they should just go out with a bang and leave it there. they shouldnt even try to get another joker cause that would be overkill.
