If you have been dreaming about your device eventually getting a taste of the CyanogenMod 9 ICS port, and are wondering if it will actually come to your device, then the above flow-chart could give you the clues you need. The flow-chart should provide a decent answer as to the chances of CM9 coming to your device. For example, the chart starts out with the most important initial requirement, 512MB of RAM or more. If you don't have that, then you can immediately stop, because CM9 will not come to your device.
Still, even with the flow-chart, it appears that there is a maximum of a 75% chance for some devices to get it, but at least you know more than you did before.
