I understand where your coming from. However, Larian is releasing a free upgrade to EE and has released quite a few very successful games. The company has been in business since like 1999 starting on Divine Divinity (a.k.a. Sword of Lies) and going very strong. They are not like most developers trying to sponge as much money from their customers with BS DLCs as they can.
As for waiting 2 years, I'm expecting the alpha or beta to be released in about a year from now. Since majority of the mechanics are completed, I'm doubting any major delays.
DLC or Expansions, Divinity 2 had expansions.. giving digitally expansions would increase the value or at least stating that if any extra payed content is created we will be given access for free.
