I wouldn't say "indefinetly", as book 12 is the final book. Everything will be ended then.

Also, book 11 is, in my opinion, one of the best so far. Lots of fighting, lots of stuff happening, several story lines finally coming to an end. Things start to shape up really. I can smell the final battle on the horizon now, and with (EXTREME SPOILER ALERT) Moiraine coming back soon it'll all be good..
