Have you read the post above you that the team already declared that the visa doesn't approve their request? This seems obvious for everyone and i think another dump will be coming as soon as possible due to the misinformation regarding the truth of monaco about visa approval.
I think that's misrepresenting the situation a little.
The card will have the Visa logo on it, it will be accepted everywhere Visa is. As far as I know, Visa didn't exactly deny their request for a direct deal, they're just still in negotiation over that. Currently they use a reseller of the Visa brand, probably at reduced profit levels, but to the end consumer there will be no difference.
Don't get me wrong, there's a lot of troubling things about MCO, but the Visa logo is, imo, the least of it's worries.
