Yes, Rockstar is heading back to the early 90s to revisit Carl 'CJ) Johnson and the Grove Street Families courtesy of an upgraded version of the PlayStation 2 classic, which features "remastered graphics including dynamic and detailed shadows, greater draw distance, an enriched color palette, plus enhanced character and car models".
In addition to the above, the mobile version of San Andreas will incorporate new touch controls, three different control schemes, and a reworked checkpoint system which will presumably remove the need to restart failed missions from the beginning. The game will be released for select iOS, Android, Amazon Kindle and Windows Mobile devices in December, with an exact release date yet to be announced.
