Absolutely not.
First of all, this is a stupid rumor that arose from a very vague comment that Elop made and it doesn't even deserve a thread, certainly not one with the misleading title you picked. I seriously doubt Nokia will go to Android.
But since you opened the can of worms, I'll bite.
Nokia going to Android would be a huge mistake. I'll tell you why. First of all, Nokia actually benefits from being an exclusively Windows Phone operation. It allows them to focus all their resources in one direction. This is why Nokia's Windows Phones are better and more unique than anyone else's. This is why Nokia has lots of excellent in-house Windows Phone software and software exclusives while the others have nothing. Windows Phone also helps Nokia differentiate their brand, which is very important in such a crowded and competitive industry.
The truth is, the Android field is way too crowded. Plenty of makers are getting pushed aside and marginalized and making only tiny profits. This is because of the fierce competition. Both from Samsung who dominates Android totally, and from all the cheap, substandard Android devices that flood the market.
If Nokia went to Android, they might have a short rise in sales, but it would inevitably be a decline. Samsung would eat their lunch on the top end, and on the bottom end they would be outfoxed by all the cheap crap Android phones which aren't afraid to compromise quality to get the lowest price. It would be an unmitigated disaster for Nokia and I think they know this.
Furthermore, Android's inherent complexity and bugginess would cheapen the Nokia experience. It would not only not allow Nokia to differentiate they brand (other than maybe some horrid UI skin) but it would also prevent Nokia from being able to deliver a consistent, reliable and intuitive interface on their phones.
Even if Nokia continued to make Windows Phone AND made Android phones, that would be a problem. The reason Nokia makes the best Windows Phone experience is not only because they are a great company, but because they can focus on Windows Phone 100%. If they had to divide their resources to support/develop Android devices too, the quality of the Windows Phone innovation they do would necessarily suffer.
Nokia going to Android would be a colossal mistake that would signal the pending demise of the company. There are no guarantees with Windows Phone, but it is definitely Nokia's best chance. I believe Elop is smart enough to realize that and I hope I am right. I would hate to lose Nokia and have to choose between Samsung and HTC devices or an iPhone. Ugh...
