No sense in commenting above.
What you are writing is not true - you can buy Tizen smartwatches in USA and Europe. Regarding the smartphones (probably that's what you had on mind) - Samsung Z3 will be launched in 11 European countries (btw. Russia is also in Europe if you haven't noticed yet).
Ubuntu Touch is not a failure, it steadily develops, step by step and devices in 2016 will have the long awaited convergence. They don't have financial troubles or employeers leaving en masse.
When it comes to smartphones, first Tizen product - Samsung Z1 was targeted at low-end, it was not meant to compete with top Galaxy models.
I'll give you an example of a much smaller team, consisting of 39 people that weren't the "best & brightest former Nokia/Meego employees" and achieved a lot.
