No I didn't.
Steam certainly isn't being dropped for Linux. Far from it. Where you get this idea or impression I have no idea. They're pinning their future on it. Millions. i.e. far more than Sailfish will have shipped in 12 months time, unless something extraordinary happens. ~3m smartwatches were sold in 2013. It'd be extraordinary if more than double weren't sold this year. Sales will explode in 2015, if for no other reason than Apple are launching their product. I'd be amazed if less than 25m are shipped. It'd also be pretty amazing if Samsung were not top 2 with Apple. So do your own calculations.
