In theory, the oculus team will have more resources at their disposal. However, they are now apart of a publicly traded company with an emphasis on meeting investors' expectations on a quarterly basis. Also, new layers of oversight will necessarily be introduced, potentially limiting their ability to pursue industry related partnerships unless FB management can be made to see the worth of such deals.

I'm withholding judgement until someone respectable like Carmack comes forward with a rationale for why this is ultimately a good thing.
