Unlike other companies which treat Windows Phone 7 as the secondary operating system, Nokia is betting big on it. That's why it needs to keep its product portfolio fresh to keep the enthusiasm alive in the market.
Nokia, which may come out with its first Windows Phone probably in September or October this year, is likely to launch newer models on the same platform every few months after that.
"We should be launching new devices in a rhythm that might be every couple of months, every three months, something like that," said Jo Harlow, Nokia's executive vice president of smart devices, to PCMag.
