We like the direction both Fiat and Chrysler have been going in, so we'd be loathe to see much change. The Chrysler IPO that had been proposed would have no doubt created a lot of changes, and could have driven a wedge in between the two companies. Said wedge could have severely hurt Fiat's transition to being a truly global company, and made the transfer of technology slower and more complicated. A full merger will help Fiat and Alfa Romeo survive slow sales in Europe and transition into other markets, like ours.
Luckily, that has been averted, as Fiat and the UAW VEBA Trust have agreed upon a prchase price ($4.35 Billion) for the remaining share of Chrysler. This means that come Janurary 20th, the two will fully be a single company.
