I think that Cadillac is
I think that Cadillac is currently building some of their most exciting cars in the brand's 116 year history. But I also think that their pricing models are too high. It may well be that GM will sell the Enspire in the U.S. as a Cadillac, as it is a great fit for the brand here, and that they will promote it in China as a Buick, and Buick is seen as relatively more upmarket in China than in the U.S. It couldn't hurt to sell it as a Buick here too (at a lower price).
