What! NOOO! Robert Sheehan is leaving Misfits?! is this for real?

i read a few articles online about him leaving and a new character called "Rudy" replacing him. seriously...the show will go down the drain without him. and if anyone can replace nathan it would have to be like...god. i am so mad. i dont live in the UK so i can only whach it online and i heard that all cast members confirmed that they would do season 3. i guess my life isnt exciting anymore... so please tell me this is true if it is so i can try to get over it and not fantasize about him miraculously showing up in season 3
