D800 issues?

Hi,

I have been lusting after a D800 since it came out, but couldn't really justify the money. Now, I can get, what I think is, a really good trade in for some of my Canon gear so it just might be the time bite the bullet.

Are there still issues with the D800, like the left focussing problem? What other things do I need to be aware of? Are there any things I need to known when switching from my trusty 5D Canon to Nikon? (I did own a D70 in what now seems ages ago)

Thanks for the help,
