I agree with you, just wanted to point out that the power meter will probably be ANT+ compatible (cycle computer included or not) since they are a member of the ANT+ Alliance.
ANT+ seems to become a common wireless standard among power meters and cycle computers. With a common standard in place it could make a lot of sense for them to only focus on the power sensor and just let it interface with third party Ant+ cycle computer like Garmin 705. And since they ask if you already own a Garmin 705 in their survey, it's very likely they wont include a cycle computer.
You can read a lot between the lines by reading the questions in their survey. Their website for example doesn't mention anything about where the power sensor is placed (like hub, BB, cranks, pedals cleats or shoes). But the survey doesn't ask what kind of hubs, cranks or shoes poeple use, but only what kind of pedals people use. If the power sensor wasn't attached somewhere to the cleats or pedals then they would probably not ask what kind of pedals people use.
