When it rains, it pours — and if this newly leaked deck turns out to be the real deal, it’s definitely pouring over at Sprint right now. Phone News claims to have gotten its hands on a roadmap revealing the entirety of Sprint’s upcoming line up for the first three quarters of 2009 and, well, things are looking pretty good. We have no reason to doubt the authenticity of the slides for the time being so we’ll let the deck do the talking. Highlights include affirmation of a Q2 Palm Pre release (shown above with model number P100), the BlackBerry Niagra dropping towards the end of Q3 and a handful of Samsung and HTC handsets that should keep the Windows Mobile crowd happy. Hit the jump for the complete collection of slides.
