I'll be particularly OK with it if it manifests itself in a larger battery as part of the mix. I now expect it to.
I think that bonnie has the right frame of mind on this. Tesla set the bar pretty high with the Model S (best car most people have ever driven) and if the X is anything less than perfect it will always be not as good as the first one. No way do they want that to happen. The only thing they can do is swing for the back fence and you better know people will be watching for any tiny little flaw. They have to hit this one out of the park again, nothing less will do.
