Your best bet right now is probably SwiftKey:

BBRY co-developed the BB10 keyboard with SwiftKey. It's not identical and doesn't have all the same features, like the word flicking for example, but does learn your typing habits.
Tracks your usage too and shows you some cool metrics like how many autocorrects and "heatmap" of your keyboard presses. And allows some customizations like various skins to change keyboard colour scheme.
There's a free version too. I haven't used either personally, so I couldn't tell you the difference there.
I can tell you I know several people extremely satisfied with the paid version.
