If there’s been a consistent complaint about Microsoft’s Surface family of tablets, it’s that the devices are not available in enough markets. That’s about to change: Microsoft announced today that Surface RT and Pro will be launching in additional markets over the next several weeks.

Finally.

“We know it took us a while, but we hear you, and are excited to be able to provide an update on the countries where Surface RT and Surface Pro will be launching in May and June,” Microsoft general manager Brian Hall wrote in a post to the Surface Blog. “Additional details on launch events, retail availability, and pricing will be provided in [the] future ahead of actual launch dates.”

Here’s what’s happening.

Surface RT

Launched in October 2012, Microsoft’s Surface with Windows RT is already available in Australia, Austria, Belgium, Canada, China, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Russia, Singapore, Spain, Sweden, Switzerland, the United Kingdom, and the United States. But that will expand to the following countries on the following dates:

Malaysia. April 25

Mexico. By the end of May

Korea and Thailand. June

Surface Pro

Surface with Windows 8 Pro launched in February 2013 and has experienced availability difficulties and is available currently online in a few markets: The U.S., Canada and China. But that’s changing big time. The following countries will get Surface Pro on the following dates:

Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Luxembourg, New Zealand, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. Before the end of May

Korea, Malaysia, Russia, Singapore, and Thailand. Before the end of June

Mr. Hall noted that Microsoft’s silence about availability expansion over the past few months was due to sensitivity about the problems it had shipping enough Surface Pro units into the market already, especially the 128 GB version. But he says that most retail partners in the U.S. and Canada as well as the Microsoft Store now have the 128 GB product consistently in stock, and it’s time to expand.

Good news all around.
