I think it's realistic to say that we are possibly within a month of release. Rejoice, brothers.
Using the power of estimation, I believe that Alex should be pretty much done doing the tutorial and have bugfixing and playtesting to do, so I'd be kind of surprised if it was more than one or two weeks.
Then again, I don't even thoroughly test my mod so it's not like I know how long it takes, I just fix things in a panic after people tell me it doesn't work.
