You should ask yourself why nokia gave up this platform. It's not in production state yet and they doubt to get it to work soon.
Same happened to vodafone/samsung with their 360 platform. It was released when it was not ready. After they realized it takes too long, they wrote off about 1 billion and stopped it.
Currently the players are iOS, android, wp7 and maybe webos.
