it'll still be airing liz.
there's 21 episodes left for them to air before shippuuden....
I'd bet:
11 more normal airings
10 episodes of some naruto marathon to get the last 10 episodes done with (cause they're so effin horrible)
believe me they're betting on shippuuden to be a moneymaker as far as ratings go cause the animation is so much better than the rest of naruto...we'll still see it.
i personally think that they should rerun deathnote once or twice its also a moneymaker
