It revealed that it will go on sale in eight countries on October 26th: Australia, Canada, China, France, Germany, Hong Kong, the United Kingdom and the United States. While it will go on sale physically in Microsoft Stores in the US and Canada, it will be an online only purchase in the other six countries.
This shows that Microsoft wants to go for a global launch of the Surface tablet. Earlier today, it was rumored that Microsoft plans to make as many as five million of the Surface RT tablets for the fourth quarter of 2012.
There are also rumors that the Surface tablet will be launched in other retails stores in early 2013, perhaps as part of the previously announced launch of the Intel-based Windows 8 Pro version of the tablet.
