Not sure how it could work out tbh. Ok I am not a lawyer or a part of the negotiations between Google and OEMs but I don't think Google can force OEMs to keep phones up to date for a given amount of time. First, it is not just up to the OEMs, they need new drivers for new platform versions. Secondly, what leverage does Google have here ? Preventing OEMs from releasing phones with Play Services looks like a really sharp double edged sword. Even triple edged actually since consumers would also suffer from this kind of deal.
