I'd rather Lopez was fit and healthy than sick and playing in Opeth. In truth we'd all like him to be fit and healthy and playing in Opeth, but that mightn't happen for a long time or at all.
But lets face facts, people leave bands all the time due to personal reasons or disagreements or whatever and it doesn't neccesseraly affet things that badly. Opeth have had different members before, and people on different instruments and ok it's not the same as when they first started but it's still great music.
Guys, if he comes back, that's awesome he seems like a top lad and a great drummer but so's Axe and if he becomes a permanent replacement then that's great. I've no doubt that any drumming replacement will be absaloutly amazing. People, just chill out.
Lopez, get well soon yea.
