Are the hardware versions sold in different countries different?

I am a Chinese user. The firmware version that 945 can be updated to through Garmin Connect is 13.00, while the forum's top post shows that 13.70 has already been pushed, [email protected] response is 'inconsistent device version'. May I ask if Garmin's products sold globally have this situation? Do I still have a chance to upgrade to 13.70?
