I'm going to say not much, other than solidify it's 3rd place standing further, for now. WP is still light years behind android and iOS and it's app selection is still terrible. What I'm interested to see if whether or not more developers - or more accurately enough developers - start developing for WP to make it's app store not suck. But in order for me to take them seriously, it's going to require a combination of Microsoft waking up to implementing all the core OS features android and iOS users have had for ages along with much stronger developer attention. On top of that, WP has another problem with limited multi-carrier adoption. It's pretty rare to see any one particular WP device widely available on all carriers.
