Yeh its way too early. Id look out for abacus for the first release, they normally release new models first although they are normally crap heaps i.e. the 787.. but yes its way to early for a 747-800 at this stage.
Maybe after roll out and loads of pictures are about the builders will get going, so I think you've got a while yet.
You cant have your cake and eat it... What the hells the point in having it then!!!
