Honestly, I'd say no.
The improved weather and such I think will add a ton to the game, which is at 600k.
But that doesn't mean you should give up hope on funding if it doesn't reach a higher point. It just means they'll need to raise more funding after Kickstarter ends.
I can easily see this reaching $1.5 million sometime in 2016 so long as they get a good system to increase funding through the website in place once Kickstarter ends, and if they improve their ability to market.
