Well theirs a few hurtles Sony has to over come.
First hurtle, home consoles are pretty much banned in China. Gaming is also heavily policed with a set amount of time a day a person can legally play games. This will make it difficult for Sony to bring PSP/2 and PS3/4 to China. Also gaming in China is riddled with piracy and internet cafe's where gamers go to play their games. How will Sony get those gamers to abandone PC's and enter console gaming. Then theirs PSN, China heavily polices the internet in their country and Sony would have to give the Government access to their servers and information so that the police and Government could monitor PSN activity.
Thats just the first hurtle. The second one is to my knowledge the Chinese Government demands that any foreign company partner with a Chinese company to distribute products in their country. The State has their fingers in almost every company in the country. Nintendo couldn't bring their consoles (Handhelds or Home) to China without teaming up with Dr.Wei Yen and a Chinese nationalized company I-Que had to be formed.
That is alot of hurdles for Sony to over come. I remember Iwata announced the Wii was coming to China ages ago. However since it never did I assume the red tape stopped them. If Sony does actually manage to bring the PS brand to China it will probubly be a similiar move to Nintendo a new Chinese company will need to be started and the chinese PSN will need to be unlinked to the rest of PSN or the Chinese Government will want access to Sony's servers and information.
In the end Google was driven out of China will Sony put up with the Chinese Government and go through all the red tape? If they do , will it really be worth it?
