As we get closer to Samsung’s long-awaited Galaxy S IV event in Times Square later today, the rumor mill is working overtime. According to a source for The Wall Street Journal, Samsung’s new handset will come with SwiftKey Prediction Software built-in.

This isn’t much of a surprise to us as the Galaxy Note II had the same prediction software built-in following its release, and it would make sense that Samsung would want to continue this deal on their most recent flagship device.

For those who are unfamiliar with SwiftKey, here is a short description of the app:

SwiftKey replaces the touchscreen keyboard on your phone with one that understands how words work together, giving the world’s most accurate autocorrect – and predicting your next word before you press a key.
The keyboard learns as you use it to make corrections and predictions based on the way that you write.

It can learn from your Gmail, Facebook, Twitter or blog to make its insights even more personalized. You can also enable up to three languages simultaneously, for true multi-lingual typing.

If SwiftKey does come built-in to the Galaxy S IV, we’ll likely hear about it alongside any other new software improvements Samsung has up its sleeve for the big announcement. We won’t have to wait long to hear about it either, as Samsung is set to unveil the device at 7 p.m. ET today.

Cult of Android will be there, so we’ll bring you Samsung’s announcement and our hands-on coverage as soon as we have it.
