According to Robert Scoble, tomorrow is not only a big day for Windows Phone in terms of launching hardware, but also for the Marketplace which will see a flood of new apps.
Not much is known as to exactly what will be released nor how many, all Scoble says is "Lots of Windows Phone 7 apps coming out tomorrow." and in response to whether they were ports or something completely different, he responds with "the apps I have seen for Windows Phone 7 are completely new".
Tantalizing. So far, the Marketplace is passed 1,400 apps as of a few days ago. It will be curious to see what Microsoft has in store for us in just a few hours. We'll be keeping a close eye and will report anything we find.
