Future Windows Phone form factors outed in presentation slide?

At a recent Windows Phone event held at Nokia World, it seems that Microsoft may have outed several new Windows Phone form factors that we might be seeing some time in the future. We already know of the existence of some large form factor Windows Phone handsets, such as the HTC Titan II and the Nokia Lumia 900, both of which feature screen displays over 4”, which makes it interesting to see what appears to be a device with a 5” display, and one that could pass off as a 1” display.

The 5” display have some thinking that it might make it perfect for competition against Android’s larger offerings, such as the Samsung Galaxy Note and possibly the Amazon Kindle Fire. The 1” display device also seems built to compete against Apple’s iPod nano which could not only target the youth market, but is expected to target the fitness industry as well in terms of a portable music player perfect for the gym or exercise.

Naturally Microsoft has not confirmed the existence of any of these devices, and for all we know those devices displayed in the slide could merely be random drawings used to illustrate a point Microsoft was trying to make. Although to be honest, it does sound a lot more exciting to think that the devices pictured above could be the future form factors of upcoming Windows Phone devices. What do you guys think?
