For those of you awaiting this model (which currently has a shipping date of Sept.'12), it's interesting to note that Lionel has posted the owner's manual, dated 6/12, in their online catalog. See for example: http://www.lionel.com/Products...neID=&CatalogId=
I can't see any surprises in the text nor anything that looks a little problematic (famous last words). I guess the main novelty is in the sound system.
However, I have never known Lionel to post the manual for a Vision product this far in advance of it actually being released. (The original ship date was this month.)
