Yes, originally we planned Don't Starve Together to be a simple update to Don't Starve. However, as we continued to develop it, we realized it needed to be a separate game altogether because too many features were diverging.
Instead of raising the price of vanilla Don't Starve, we kept the same pricing for Don't Starve, and created a bundle for Don't Starve and Don't Starve Together, giving all players more choice.
To wrap up, instead of simply updating Don't Starve, we have made Don't Starve Together a stand-alone expansion, and we have gifted the game to all Don't Starve owners on Steam on June 3rd, 2015.
