According to the folks over at Allpar.com, they nixed the idea of direct injection due to noise concerns in the Grand Cherokee. Other incarnations of the engine are likely to have it, and it may eventually come to the GC, but I've yet to read anything about an expected or estimated date.
My own guess would be that DI won't show up before an 8 speed transmission.
