We first mentioned SwiftKey way back in July of 2010. Back then, it was kickin' the stock Android's keyboard on a Google Nexus One. Since then, many enhancements have occured to make it better and better; a lot of people agree that SwiftKey is one of the best keyboard replacements out there.
Today, the beta for SwiftKey 3 was released to VIP members.
As far as new features go, the keyboard has gone through a complete facelift (which is sexy), increased the size of the spacebar, added more languages, and added a nifty punctuation button (similar to what the ICS keyboard has). The biggest feature that was added is the ability to find spaces. SwiftKey has always been good at predicting words, but now it can see where you missed spaces. You can type a whole sentence without touching the spacebar, then tap the period button, and the spaces appear![Android Police]
