What Is The Sony Ericsson Xperia Ion?

Will Sony (once dropping the Ericsson bit becomes final) be adding a model to its Xperia line of Androids called the Sony Ericsson Xperia Ion? That's the latest theory going around, thanks to the discovery of the product name in a trademark filing with the USPTO. Just what might this hardware end up being?

What is Sony Ericsson Xperia Ion ?

For the moment, at least until we learn something else that helps to narrow-down the field any, the Xperia Ion is a potential name for any of the Sony Androids we've learned of being in development. We recently saw some pictures snapped by the thirteen-megapixel LT28at (Sony Ericsson Xperia Ion), and its Bluetooth SIG paperwork claimed the phone would see a release in North America, presumably continuing the Xperia name. While nothing specifically ties it to the Ion, it's as good a possibility as any.

There's also the possibility that the Sony Ericsson Xperia Ion will be a new name for some hardware we've already heard identified, like the Nozomi. This seems like a less likely possibility than something like the LT28at (Sony Ericsson Xperia Ion) taking the name, but it's still one to consider.
