I've asked for some clarification over what 'upgrade' options are available for those at the boxed physical PC tier, as it's not covered by what they've announced today. We should at least be getting both a PC and console copy of the game, but no word on the ability get a
physical console copy.
Edit: just reading back over their replies on Twitter this evening, there's this:

@PlaytonicGames If you backed the physical PC edition, can you change that to a physical console edition?

@joggingkangaroo You can change your additional digital code. PC physical is KS exclusive and unfortunately already manufactured

Of course, we could just sell the code and buy a physical copy - it'd probably actually work out cheaper than changing via Kickstarter!
