A bit of a late post, so most of you have probably seen this already.

It looks like the cheapest virtual only buy in for the full game is $150, while the cheapest physical full game is $195 (+shipping/import tax!)

There are some links in there for some early reviews and play-throughs too. These only look to be the Stormlight system though, so I assume the Mistborn/Scadrial (an any other planets) are still in the works.
