I think the CE has already lots of value in it. Only the 2 steam keys are almost 80 Euro right now. And on top of this we get lots of other stuff.
I don't say I'm not disappointed a bit, but I got over it.
If you have bought Divinity Anthology CE, you'll notice that, in reality, it is a little bit disapointing =p
The real selling point is the 2x steam keys.
