If you do pick the PC version, you'll have the option of getting a Steam key on top of the EGS release.

You should see a similar approach for other titles going forward. Tim Sweeney has promised that Epic will either ensure refunds for crowdfunded games that go EGS-exclusive or "coordinate" with people at rival stores to lock in key availability. It's not certain if this will always lead to Epic paying out of pocket.

This move won't address the core complaint -- namely, that backers who were expecting Steam releases are suddenly forced to either hold their noses and use EGS or give up on a game they'd wanted for years. It might ease some of the pain, though, and any direct compensation could ensure that games still reach the market. This might also help Epic gauge the effect of wooing developers of crowd-supported games. It would just have to look at refund numbers know if there was a serious backlash.
