Just like the title says, a couple of online retailers are breaking the street date and shipping immediately. NCSX (an import retailer and official importer for 1up.com) has both versions in stock for $60.90 and offers overnight shipping, albeit at a high price. Newegg is also offering the games for $56.99 each. Both offer same day shipping (NCSX before 5pm EST and Newegg before 3pm PST) and are quite reputable.

I know these aren't exactly deals, but if you want it a few days early then these are certainly an option. Hope this helps some people out!
