According to an update on Dawntide's official website, that hiatus is now going to last quite a bit longer because the dev team has run out of funding. "We're still working on finding new investors, but this will take time. In the meanwhile, we have officially stopped all development," the announcement says. "We hope to be able to resume it in the not too distant future, but as of right now we cannot say when that will be or whether it indeed happen at all."
