I'm not sure what more you could ask for...we have numerous occurrences of the developers supporting the same statement. Even from this question and response, from a month ago, to just a few days ago, they've said the same thing - mid-December. As well, one of the devs who frequents /r/Hoggit has hinted severely on several occasions in the past week that we will see it soon, his excitement is made more obvious by the tone of his responses.
You won't get a massive flashing neon sign? It's not going to get much better than this, and I'd say it's the wiser method chosen by RAZBAM. Far too often a date is set that can't be kept, which leads to massive disappointment.
The consistency and frequency of these - not just hints, but - straightforward and more-than-obvious remarks are more than enough for me, personally. I guess we'll find out soon!
