At WWDC, Apple has announced QuickType for iOS8: a new feature that'll provide content sensitive next word suggestions to users. For example, if a user is replying to a message about going out for a movie or dinner, 'movie' and 'dinner' could be suggested as words to use. QuickType will also learn how you type and will provide suggestions based on that, meaning that words like 'epic' and 'awesome' are more likely to be suggested if you commonly use those words. International users will also be happy to learn that QuickType will work in multiple different languages, not just English.
QuickType will make its début in iOS8 when it releases.
