You're probably right. It just seems as Eric said that the Samsung shills will be out in force and correct anything they (Wikipedia) might try to factually edit. Still though it's better to correct such errors rather than let such lies fester.
Many tech companies have clauses that cover this but find their products sold before official release dates anyhow. I recall this happening to Microsoft with their X-Box and I think even Apple's had some iPhones ship/sold to customers before the official date.
