Lack of BD-J Titles?

[GetSmart]

So in my research I can only find BD-J Titles from two studios:

LionsGate (under 10 titles)
Disney (under 5 titles)

With all the Blu-Ray titles out there and the fact there are tools such as Sonic's Blu-Ray authoring tool and BluPrint from Sony that can create BD-J titles.

Why the lack of titles?!?!?

Especially from the two big companies that back Blu: Fox and Sony?

I'm hoping for the AI game like the one found in the movie 300 (amazing, absolutely amazing the game plays in real time against you!) This is what I expect from BD-J. I wouldn't expect it from HDi. But then again look at how far we've come with Java Script. Google Maps comes to mind it's all Java Script.

Anyone know why Sony and Fox don't have titles, or if they are going to soon? And aside from Disney doing its line of titles in 2008 anything else being released before the end of the year?
