I agree with emi above.
It happens that the subject of the thread is A, and person 1 and 2 actually discuss about A (on topic), and that sometimes the 'discussion' contains off topic elements; B (because some people go in deeper into the subject and stuff). It's only normal to get off topic, if anything every thread contains a lot of off-topic-ness
(what), I don't think the threads would live that long without them. <I'm pretty sure everyone knows that, yet it's weird to some don't think of this.>
And it's not like there is total "my opinion has more value because I'm smarter" crap or something going on, it's pretty civil in every thread. But I can understand that it's annoying for people to think that every time someone posts in this thread new news arrives. But really what can you do?
I have the same with the Tales of Xillia song thread, I keep thinking the trailer has arises, while we're probably not even close to the actual trailer release. You don't hear me whining about it

. And really, everyone is being off-topic every once a while. Saying crap like "
I thought we got tons of information but it's just people being off-topic and discussing the same thing all the time" and people acting like they're on-topic all time is what should get the negative focus instead of the (casual) off-topic discussions.
It's up to the mod to remove the posts which are seen as off-topic, and the mods will delete them or place them in the trashcan.
What are forums for anyway?
