After the massive success of the HD conversions of God of War titles I, II, and III, it appears that the two PSP God of War games are coming to PS3. According to the site The Magic Box, Sony Computer Entertainment Taiwan (SCET) has announced both God of War: Chains of Olympus and God of War: Ghost of Sparta will be making their way to the PS3 in the same form God of War: Collection did. The PS3 title will gain higher resolutions and enhanced graphics. Releasing in Asia on July 7, 2011, God of War: PSP Collection will come in both English and Chinese versions. However, It still remains unclear whether a western release will be made, but it is highly expected that this should happen, so stay tuned.
