'CSI: NY' Sneak Peek: Langston's Cross-Country Trip Drops By New York 

This whole thing is simply a ploy to get people to watch CSI again (hence the last and important part of the trilogy ending in Las Vegas). To be honest I have no views on Langston since I stopped watching CSI when Warrick died and I found out Gil was leaving but him being the one who goes to Miami and NY just proves my theory of ratings getting. I may be wrong here but wouldn't it make more sense to send Catherine? She's already worked with the Miami team and she is the new boss, right?
