It looks like HTC is firmly on board with Windows Phone Apollo with plans to launch new devices when the Apollo update hits later this year.
Kouji Kodera, HTC's Chief Product Officer stated,
"For Windows Phone we haven't decided on the branding yet, but you will see a new range of Windows Phones from us when Microsoft release their new Apollo operating system."
Kodera also confirmed that the HTC Titan II, that is due on the AT&T network in March, will eventually find its way outside the U.S. Market. He didn't get too specific on where the Titan II would land or when but did note that Australia would be getting the 4.7" screened Windows Phone.
