I dunno. If his ETA at the time was September, and we were close to it, then it means things were relatively nearly done. Of course, when programming complex things like this, delays just happen. Things pop up and that leads to other things. And it takes up to a week to get a response from the freelancer side. And not only that, but I seem to remember Red51 saying that a lot of code had to be re-written. This might seem to many as "but it's just editing code that's already there. That must be super easy!" But no. In my experience, re-writing code that was already there can be *worse* than writing it from scratch. Code is a funny thing. It's written to work as it is, and of course you want to edit as little as possible because if not, then a lot of your work goes to waste. But in the end, if you change one thing, you don't just do that. That one thing affects a million more things and you have to chase the effects down. If you're a writer, then you might understand it in terms of a story. Change an early event and you'll practically write a new story by the time you're done adjusting everything to that one event. Programming is the same way.
That said, if things were nearly done, then there's only so many things that can then go wrong. I'd expect up to maybe a month of delay? Yeah, I guess it's possible that every thing that can possibly go wrong will do so and then we'll get the update early next year. But, come, now. The chances of that actually happening aren't really that high. I'd say we're most likely to see it this month, rather than later.
And man. Red51 keeps stressing that it's a really big update. Beta incoming?
