I love Lateralus, think both Aenima and 10 000 Days are great, and I enjoy Undertow.
However, Tool are not among my favorite bands. So in that sense it doesn't bother me if it takes time. It's not like I'm going around waiting for a new album, when/if it comes out, I'll be happy and I'll check it out, but I have plenty of other music to keep me busy.
