Joder Bagman ... es que son ganas de tocar el bajo vientre al foro (y en especial a los poseedores de una PS3).

Veamos ...

De tu primer link se lee:

Update: CVG states that they have received confirmation from Rockstar that “both versions of Grand Theft Auto IV will have an online multiplayer component”. [Thanks LC]
En tu segundo:

A Rockstar rep has told Next-Gen that both the Xbox 360 and PS3 versions of GTA IV will feature online multiplayer modes.

"As we've said previously, both versions of the game will have an online multiplayer component," said the rep via email.
Y en el tercero:
The revelations came during a podcast with Xbox Live big-wig Major Nelson, leading some to interpret that, come launch day on 29 April, there would be no multiplayer mode for the PS3.

But fear not, PS3 peeps. Game creators Rockstar have acted swiftly to quell the rumours by saying that both releases will have the killer online play feature.
Paso de traducirlos ya que entiendo que no te hace falta (que conste que no lo he dudado en ningún momento) pero claramente el movimiento del bocazas del Major Nelson fue para crear hype a los Xboxers e intentar joder a los Sonyers. Punto. De ahí lo del marketing.

Si te gusta meter ruido en el foro ningún problema ... go ahead !

Saludos a tod@s
