I see where you're coming from and you're right it will still be very good later but at this point I know very little besides the starting area.
In 6 months time I will know a lot more about the world, story etc. whether I like it or not, unless I choose not to visit social media/forums, follow gaming news or listen to podcasts anymore.
Exploring this fresh and new and having that buzz from discussing with others who are also doing the same is a big part of the experience (for me at least).
And price wise I don't think it's going to get that much cheaper, console or the game, this is Nintendo
Just look at the price of the Wii U.
