Will KSP have physical store-bought copies after release?

[KSK]

I prefer a physical copy always above a digital download. Why? Because I play games 10 years after the were released (e.g. the Age series, Black & White, Robbin Hood Legend of Sherwood, etc).

Also I don't like the idea of paying for something really awesome which might not exist anymore after 7 years... and with a digital download.. well you can't do much about it when it's gone.

A physical copy allows me to backup the disk(s) and ensure me that I still can play it after all those years, which I still do with the above named titles.

Besides this: KSP rocks! I would love a nice boxed collectors edition just because I love KSP, I love collecting and Squad deserves the money for it! ;D

This. Exactly this. Doing it via Kickstarter sounds like a good plan.
