2015 Colorado, new stuff?

I am just viewing the news about the 2015 Colorado, looks enticing, has the rear hinged rear doors on the extended cab version which is not available on the full sized Silverados now. The Canyon GMs offering looks stylishly more rugged. The engine selection is decent but the best news is that a 4 cylinder Duramax diesel will be a future option.
Pricing will be nearly identical to the Chevy Equinox which has me also interested as I just bought an awesome 2012 with the 2.4 and I really like it, but its the wifes car, I need a truck for me, my 2002 Silverado dually is just a big too big for my needs lately.
