I recall there being some big delays getting Skyrim's DLC to PS3. It wasn't out of malice, but instead their struggle to overcome some technical issues. With porting Online to the current gen consoles, it's entirely plausible that they're simply unaccustomed to dealing with these platforms and it's taking longer than expected.
