Shadows of Esteren Kickstarter : update and new cover art?

Shadows of Esteren has updated their Kickstarter campaign, giving you, the backers, a say in how the stretch goals for the campaign play out.

From the update:

We have been sent a lot of messages, and some of our backers mentioned new ideas for future stretch goals. Many things, and plenty of interesting possibilities! Since we want to provide the best, we have devised an alternative journey for Yldiane with new stretch goals : A pronunciation guide, a Game Leader Kit or some cardboard tiles, etc.

We propose to our backers to choose between the first route and this new route. However, please note that this is not a meaningless choice, because it will alter many of the steps to come!
