I purchased on Monday and asked the same question to Jake at PIU. This was his response:
"We carry the newest version of the CFV with the corrected airtight mouthpieces - the leaking problem was solved before release. =)"
Sorry Chandler, that was me. I based the Michigan thing purely on the SMS phone number listed on their website. It's a 269 area code which is Lower Michigan. Anyways I'm waiting like you; my CFV departed Los Angeles yesterday.
