Nokia to release 40 handsets by the end of 2011, 12 smartphones
Additional details are not disclosed, but it is suggested that all these phones will be powered by Symbian, which reiterates the rumor we are not to see a WP-running Nokia handset before 2012.
It's unknown whether these handsets will be low, mid or high-end, but it's implied that Nokia will rely on the sheer number of these phones to grab some consumer love for its native platform.
It's important to note this is not exactly a confirmed information, so treat it with a pinch of salt until more official info arrives.
