yes, it's true past examples have companies keeping their customers in the dark, scamming them or flat out lying to their faces as to the progress and expected release of the game. i for one would hope to never see TWI to stoop that low. i can't imagine an already contracted publisher would be left completely in the dark as to a broad date for when the game would be expected to get released.....while they may not know the specific date, the fact that they (1C) stated 2010 indicates that they were given a general time table as to when the game would be ready. if 1C, for example, had absolutely no solid evidence to support announcing a Q4 2010 release, then for the expected release date they would simply say "TBA". as those past examples have already shown, publishers don't want bad PR by posting any type of info, such as a potential release date, have it not be correct, and then look stupid as a result.
you see, there's a different between blind speculation and informed speculation. when all the various pieces are added up, they all point to a release sometime this year, 2010. that is informed speculation whereas blind speculation would be saying something like was first stated in this thread "April 2nd 2010 release" as there has been no information whatsoever that would point to that date.
regardless, nesto is correct in saying that all speculation is still speculation without concrete proof. however the point remians that by you saying that somebody else is speculating, you are also speculating that they are incorrect.
who knows, the other guy might actually turn out to be right....i mean here we are speculating everything from April 2nd 2010, to July 2010, to 2011. any of those could end up being correct .at least it provides TW with some entertainment in the mean time
time will tell.
