In regards to the CE, all that statement means is that it basically sucks for the SEA backer to have to sell off all his bonus Steam keys just to try and break even with the Kickstarter backer
You mean all the Steam buyers that actually want the physical CE, and didn't know before they bought that the digital and retail versions would be separate? I'm thinking that is a very small group.
The only problem with this brought up in the Steam discussions quickly became moot when it was mentioned there would be a digital CE and an upgrade option.
