The commentary from certain people. 

You know that people always jump into these kinds of threads, especially since as of late, every Forza and GT thread has become a bash fest for each opposing side. Even level-headed people sometimes fall for it as well.

Forza 3 should get pretty close to the sales of Forza 2. The 360 has a considerably larger install base now than when Forza 2 launched back in 2007. Around 20 million systems more have been sold in between the launches of Forza 2 and Forza 3. The increased install base results in increased game sales. Forza 3 could be bundled as well which would also assist its sales.

all I know is Forza 3 is tight. I actually made me go out and pick up a 360. I love it and It will hold me over just fine until GT5 drops.

I think you have missed the point. When you bundle a game (especially in the case of Forza 2/Viva pinata which was an official microsoft bundle that ran over the christmas period of 07) you artificially inflate the sales. So you cannot say that demand for forza 2 had increased by 130% over the first as someone stated.  For a long period of time in australia if you wanted a xbox 360 pro console you got forza 2 and viva pinata with it and there was no other way to buy one.

I recall a few "wars" over GT( 3 or 4...I don't remember) sales numbers and being bundled. I actually agree with you that bundles do not necessarily constitute sales numbers, however, You must keep in mind that the price of the game is factored into the price of the console, likewise, many people may have bought the bundle because they were planning on purchasing the game...and if you can get the console and the game at the same time, why not?Either way, bundles or not, this is the way everybody figures sales. So it IS fair game. Stop whining and deal with it.

At no point have I "whined", so please, take the rod out of your rectum, and stop thinking your better than everybody else.

Hmm, after just having finished reading this thread I must say kowenicki is the only one who has been crying.

Talking bundles, shouldn't there be differentiated between bundles where one get the game for free(or with a discount) and bundles where the game's usual price is added(+ the preice of a steering wheel, which I'd see more as a collector's edition)?

That was a beefy article.

So according to the article Forza 3 will sell more than Forza 1 and Forza 2 combined. Forza 3 will sell 5 million+ copies - FTW. Every Halo game sold increased sales. Halo sold 7 million, Halo 2 sold 8 million. Halo 3 has sold 10 million (13 million if you include the sales of Halo 3:ODST).
Increasing sales over time so: Forza sold 1.5 million + Forza 2 sold 3.5 million or 4 million according VGC numbers. Forza 3 will sell ltd sales of between 5 to 5.5 million units.
