It says about a site that has some info on what kind of music we can expect to see and maybe about and online multiplayer mode.
I'm not sure how reliable the source is but here's what it says:

GTA: San Andreas Info
Want to know what music you’ll be listening to and the possibility of online play you say…
New information on GTA: San Andreas today came to light, giving some insights on what to expect from the third title in the GTA3 trilogy.
Realising that the series needs further innovation, RockStar north are currently implementing a wide range of gameplay additions, including the ability to challenge fellow highway drivers to a race; however sadly RockStar North are refusing to divulge anymore information prior to E3.
Following on from the musical success in GTA: Vice City, RockStar have once again been signing up major artists, reportedly including the likes of 50 cent, Justin Timberlake and Happy Mondays to mention but a few – hinting that San Andreas will have a more modern theme then the 80’s induced Vice City.
In addition it’s claimed that San Andreas will be much larger then either Liberty City or Vice City before it, whilst we’ve heard suggestions that an online multiplayer mode will surface and provide the major selling point for the title.
We’ll hopefully have more information soon.
