:I would prefer this discussion take place in the article talk page, where more of the article's active editors can participate. I'm a bit busy at the moment, so I won't be able to fully respond until later.   

 :: It is only me and you involved in this conflict, so I find it better to sort this matter here. When you have the time, please reply. It would be conveniant to reply on . Thank you.   

 :::It's not just you and me; editors such as Silver Edge and Theaveng also involved themselves in making changes to the statements in question. Even if we were the only two editors currently engaged in the dispute, to me this is not a personal matter of conduct or opinion, but a discussion of article content, in which other editors should be free and encouraged to participate. It is article-relevant, and not the first time there has been reverts regarding this sort of content. To address your specific points, though: 
 :::Live blogs are often imprecise about the things they cover, as the reporters rush to get the information out as soon as they happen. Sometimes they get the details wrong. I'm not saying that is the case here. I already mentioned that executives often play loose with the terminology when proclaiming figures, even if there is a slide presentation with graphs. I haven't seen the graphs, so if you could show me some that you believe support your case, please point me to them. 
 :::Corporate press releases, on the other hand, are usually much more precise in what they claim, being very deliberate in their word choices. The particular press release I cited was released almost immediately after the keynote, indicating that it was probably prepared before Hirai even made his speech. I suspect it may even have been prepared with the same notes Hirai used for his keynote. As for the whether a statement that "over 120 million PS2 units shipped worldwide as of September 20, 2007" is incorrect; it can be somewhat misleading in that it may imply a stronger connection between the figure and the date than is actually the case, but to say that is incorrect is pushing the limits of literalism, in my opinion. Especially when you are trying to make an argument that as many consoles had been sold already by that date. All the links you've provided point to articles that are casually-worded. The Tiscali article was written July 16. 
 :::Sony only changed to reporting consumer sales figures with its first quarter of fiscal 2007, and even then, its internal data only goes back to fiscal 2006. Before that, the internal sales figures it reported were always for production shipments. This particular dispute reminds me of several other sales figures disputes, particularly this one regarding PlayStation 3 sales. You may wish to review that for some background. 
 :::These aren't the only issues I have with the statements, but I'm serious about my preference that this discussion take place in the article talk page. We can discuss my reasons why here, but I would request that any further comments regarding PlayStation 2 article content be made in an article talk page thread.
