Contrary to the G1 the G2 won't have a keyboard and the display is replaced by a touchscreen. Thus the mobile phone is slimmer than the predecessor. HTX, the Taiwanese producer of the G1 and G2, is supposed to be close to release the new Google phone although the G1 has only been available for about four months in the USA and the UK and has just been introduced to several European markets. The first pictures already occurred on the web. According to those images the G2 will have a 3.2 megapixel camera.
Further details, like prices or an exact release date, have not been available, but the Google G2 is supposed to be released in May 2009.
