i would think that it would be offered to original supporters, with the redline being less of a hit than expected, i don't think they want people badmouthing saturn/the redline because of that. though i think if there was an upgrade there will probobly be a few hp squeezed out of the engine, unless they really want the cobalt to be better, but i figure the cobalt/redline to be like dsm's of the past, being the same car really, just sold under different names.
only difference i think is the transmission, though i could be wrong, anyone know for sure, i thought i read that it was specific for the cobalt, which hints to me that it is not on the redline
