I'm with Neutro on this. The issues we face are not solely caused by this, but remember how things were at the end of 2011 start of 2012. IMO that was the result of too much going on.
If the factory has to make 5 items instead of 2, of course there is more pressue and more room for error. And having more items hits every point in the process; from the 4HM being able to sculpt, to Toy Guru diligently looking out for QC issues , to the factory producing the item.
