Hi. I'm voting for Chinese translation. Additionally:
1. I think I'll buy the Steam version since Steam support Alipay which is widely available in China.
2. Torchlight2 has reached out for 3DM for translation. They're doing a lot of 3rd party translating for quite a long time and really did good quality translation. I think this might be helpful.
Otherwise if Chinese localization is supported I'll definitively buy it on steam release.
