1. On 8th May 2009, the DNF team at 3DR was laid off due to lack of funds to continue development. Please keep this in mind, in hind sight, we now know DNF was supposed to go Gold on 1st April, 2010 had development been continued. This means the team got laid off with eleven and a half months work remaining. I think it would be safe to assume that this 11 and half months work would have consisted of finishing off levels which were not complete and doing rigurous QA leading to the final delivery of Gold code on 1st of April 2010.
2. On Nov 26, 2009, Scott Miller wrote on Facebook "Duke Nukem doesn't stay down for long." This was quickly followed by a "D-Day" preview pic on Nov 28, 2009. Now lets try to figure out the meanin of "D-Day". According to Wikipedia, "D-Day is a term often used in military parlance to denote the day on which a combat attack or operation is to be initiated." Wiki also suggests this day may be a variable day, but a significant day on which a significant even will occur or have occurred. Reading this meaning of D-Day with "Duke Nukem doesn't stay down for long." leads me to the conclusion, that something related to DNF has happened on or about Nov 26, 2009, and hence the D-Day pic on the 28th of Nov. With the DNF team already laid off on 8th May, I can only conclude that on or about this time, a 3rd party developer has been assigned the job of DNF.
3. Confident that DNF will be in finished state before the Take 2 court case comes up, and hence Take 2's case will be blown away, Scot then posted on 2nd Dec in Facebook "These guys don't stand a chance" and "Heh heh, who am I talking about? You got two guesses. ". Clearly Scott was Scott was super confident to blow Take 2 away after the events in Nov 26, 2009.
4. On December 7th, Scott couldn't hold it any longer and blurted out "Duke Nukem says it's gonna happen, and when it does, shock and awesome. " See a pattern evolving. Something significant happened on 26th of Nov, hence the D-Day pic on 28th of Nov, the confidence that Take 2 doesn't stand a chance on Dec 2 and finally the above on 7th Dec, 2009.
5. On Jan 7th, 2010, Scott writes "The Voice of Duke Nukem Facetiously Confirms Duke Nukem Forever ". Now this is Scott who is posting this, not us blind Duke supporters. My conclusion, Scott just indirectly confirmed DNF. And we all know what the Voice of Duke said on that day. So definitely DNF was in development in that time, and John St John knows it. And he is not allowed to say about it because he is under an NDA. So he says to "read between the lines".
6. On May 18th, 2010, Scott posted "ripped off its head, and read the newspaper." And now we know this refers to the settlement of the case between Take 2 and 3DR regarding DNF. Now what does "ripped off it's head mean". Definitely means that 3DR has basically ripped T2's head off. How that is the question. The answer lies in T2 removing all DNF related material from it's website. My conclusion, whatever the deals of arrangement is between T2 and 3DR, T2 has lost the publishing rights. They are no more associated with DNF. Their publishing right have been ripped off. Hence "ripped off it's head".
7. Finally now that the court case is over and Take 2 ripped off it's publishing rights, when can we expect DNF. Remember point 1 above. When the DNF team was laid off on 8th May 2009, about 11 and a half months work was left on DNF to go gold on April 1, 2010. So if the development re-started on 26th of Nov, 2009, it would be safe to assume that DNF will be in Gold status or very near Gold status somewhere around December, 2010.
8. And then recently, on June 6th 2010, in a Facebook reply to "Partha Nandi" when "Partha Nandi"said "Get over it man, DNF is over now

So my conclusion is with a 3rd party developer taking over development of DNF on 26th of November and adding about a years left work on it, we should see DNF this Christmas, 2010, probably under a new publisher as Take 2's publishing rights have been "ripped off".
