A recent post from Digitimes suggests that Windows Phone 7 Tango update would go live in March or April, based on Microsoft’s roadmap for Windows Phone outlined in a rumor.

The largest update, Apollo or possibly Windows Phone 8, was slated for its expected late 2012 release. However, a “large volume” of devices based on it would ship in the initial half of 2013.

The Tango updates are believed to be adding support for true native apps, more languages, lower memory requirements, and support for lower resolutions to cater to a primarily Asian demand for cheaper models. WP8/Apollo would fundamentally change the architecture to bring in similarities to Windows 8 without sacrificing app compatibility. It would get some Skype integration and support for considerably more modern hardware, such as multi-core chips, microSD storage, and HD displays.

Early supporters of Windows Phone 8 weren’t definite and appeared to be more speculation than definite fact. Dell and HP were floated as possible candidates for a comeback with Acer making a sequel. HTC, LG, and Samsung were put in some doubt after having been burned by low sales, although it’s doubtful they will drop Windows Phone given the likely discounts on Android device royalties they get for making a token amount of Windows Phones.
