Its not just the technical challenges that need to be looked at though. I was under the impression that X-box Live wasn't ideally suited to MMO style games due to the restrictions of it being a losed system. Sony allow a lot more when it come to PSN, giving developers more freedom. I was also under the impression the MMOs would be quite installation heavy (I know they don't have to be, but surely its better having the majority of the game on a HDD then on optical?) meaning the disk speed issue shouldn't be such an issue. And don't the 2 HD consoles have a similar total amount of RAM?
But yeah, PS3 harder to develop for, so making it the lead makes sense.
