is there going to be any tournament support for stores?

There will be Game Night kits released. Most likely with the rest of the 4th quarter LCG kits whenever they get released. Current LCG's are on 3rd quarter kits which you can see here, www.fantasyflightgames.com/edge_news.asp Each is $17.00 USD plus shipping costs can be ordered by those with B2B accounts which is usually just stores.

There is also a quote on that page which directly answers this question " Furthermore, Game Night Kits for Android: Netrunner The Card Game, The Lord of the Rings: The Card Game, and X-Wing™ are currently in development and will be made available later this year."
