Power of Two Games; Is that XNA company?

The author in "Games from within" has started new company "Power of Two Games". I'm surprised at his comapny. His company staff number is only two! And, why do they work in such narrow space...??

But, this is interesting news for us. He said about his dream before. Perhaps he and his co-worker try to develop games by XNA. He has tried to introduce Test-Driven-Development & Refactoring. On those categories, C# is excellent than C++. He said the same thing in fact in that entry.
