I agree with you on the need for a userbase. WP7 is currently at 2 million+ devices, which is pretty extensive but there is less competition than there would be on Android as there are fewer apps. As a result, the uptake on people buying your software might be higher in WP than on Android (a gut guess, I must admit, but it's what's prompted me to write the article). I don't think Google will drop Android completely but I think that the fragmentation will get worse. For example, I'd develop for the Kindle Fire version of Android before others. Why? Because monetization in the Kindle app store seems to work better (there was an article on HN about this a few weeks back). I agree with your last line and that's where the Motorola acquisition is puzzling. It strikes me that HTC, Samsung and others may start looking at WP as an alternative now that Motorola is owned by Google. If Nokia shows sign of strength (and early indications point that the Lumia 900 is heading in the right direction), others might follow... and THAT is an issue for Android.
