Starbucks Trenta not available yet

Recently, i've been out to Starbucks in the Metro, and i was asking if Trenta is available. The barista, (sad to say) don't even know what i'm talking about. I had my post before about the Starbucks' Trenta cup size, expected to debut on the first week of May 2011 where it's supposed to be available only in the United States.
And i was anticipating that this would sooner roll-out to the whole wide-world wherever there is a Starbucks coffee shop. The buzz has subsided, and i'd had my confirmation checked that the Trenta isn't at all available, at least outside the US just yet.
