X-Men: Battle of the Atom - anyone reading?

Has anybody been reading this story arc?  I've been keeping up with it and was hoping someone out there might want to join the discussion.  I'm hoping this to be a SPOILER discussion thread, so be warned.  So, has anybody else been keeping up, and if so, what do you think of the whole "X-Men-have-traveled-through-time-so-much-that-they-can't-anymore" explanation?
