This bet of the PS3's success this bet has shown a general decline in value from 50% likely to under 10% at its lowest. There has been a recent upsurge in the value of this bet. This means people are starting to believe it is more likely that the PS3 will win the console war. Some possible explanations for this are that betters believe that
1. The victory of Blu-Ray over HD-DVD means that people will now buy the PS3 as a media player.
2. The Xbox360 will be replaced by another console
3. The Wii’s popularity is a short term event.
