I'd argue that neither Halo Wars or ODST was a failure. Halo Wars was both a quality RTS and, if I'm correct, the best selling console RTS of the gen? ODST sold a LOT considering so many people essentially already owned half of the package. And it still sold more than all but 8 titles on the 360.
I'm sure MS and Bungie are very pleased with the state of the franchise and the possible sales numbers headed their way this fall.
