I think you mean nostalgic gamers, not developers. They're not getting that much money just from other developers.
But why not? There are quite a few businesses that basically run off of Kickstarter. Like 30% of the board game industry nowadays fund most or all of their prints runs off Kickstarter, including some of the largest board game publishers, like CMON, Awaken Realms, AEG, Eagle-Gryphon, Garphill, Greater Than Games, Renegade, Portal and Queen Games (lots more publishers than this too).
