>BTW, as the smartphone market being now almost saturated (from what I see in public transportation), unless this Chinese OS pays his clients, I doubt it can gain a place, except maybe in countries with a lower rate of equipment. That'll cost huge spending on marketing and advertisement, they better have a solid business model behind…

Not only is the market saturated, entry cost HW is powerful enough to run the OS - the bottleneck moved to the "typical" web site being overloaded/overanimated/overpictured, especially in areas where the infrastructure is not that high. But that will be fixed before another OS might establish itself.
