Polyphony Digital has been pretty busy lately with Gran Turismo for the PSP and Gran Turismo 5 for the Playstation 3. Both projects were announced ages ago for their respective system and are close to being completed.
Polyphony Digital apparently had to hire extra staff members in order to get their ambitious projects ready. On their corporate profile page, the development studio disclosed that they have around 110 employees. In the newly opened SCE Worldwide Studios website, that figure ballooned to over 140 staff members, which is at least 25% more than before.
Gran Turismo for the PSP will be released on October 1. No release date for Gran Turismo 5 has been announced yet but many speculate that the game will launch on the Playstation 3 before the end of this year.
