Most of the other projects have been posting updates so they definitely are working on the products. Unless those devs are really in dire straits it would be kind of silly for them to abandon the games.
They already have so much time put into development and the point of a kickstarter for games is not to make a bunch of money on the kickstarter. It is to make a bunch of money on selling the game since a publisher isn't basically taking everything on the actual sales of the game. Then there is more money to be made on actually getting to own the IP because you didn't get gouged by a publisher.
If they were going to run off with the money they already should have by now. At this point it is really in their interest to finish the game.
It isn't a guarantee of course, but it seems much more likely now then it did when the games were initially funded.
