If you notice they say no option for several players (more than 2) and it's Sam Houser not Sam House also it says that they denied the presence of a multiplayer way, online as as much cooperative.... Well we all knew it was not going to be an online game but that still does not say that their will not be a 2 player mode just no split screen 2 player...
and after just reading what take 2 spain said it looks more like they are just tring to ensure that no one thinks that SA will be an online game or have a (split screen) two player mode...
(It's not like a magazine to post inaccurate information)
http://news.spong.com/detail/news.asp?prid=7803 the spong article also says that the nature of 2 player is still uncertain, but Rockstar has emphasised the fact that "GTA has always been a single player game." This statement, when taken in conjunction with Rockstar's current denial of a two-player mode, leads us to believe that it will be more of a sideline component - an ancillary option rather than a central one. If Rockstar was to announce that it did have a two-player mode, people might expect a full split-screen mode or full 2 player game, and so understating this feature prior to launch should add to the impact of the game when it does hit the shelves, rather than leading to disappointment or dashed hopes.
