Is the release date already confirmed? I thought it was only assumed that it would be released on the 26th.
A friend who knows more about Japanese says that the sentence talking about GojimajiP is complicated, but is in fact confirming that they are the same person. Are you sure about your interpretation?
Since it seems that even NicoPedia editors aren't certain, I'd keep this as is for now, and possibly mention in the notes that they're thought to be the same person, but not for sure.
Hard to say. Based on the NicoPedia article for GojimajiP it seems that his identity is uncertain, but obviously they've been thought to be the same person, GojimajiP being used more for UTAU/experimental stuff. Vocaloid Wikia says this as well, meaning they'd also be wrong. I wonder how certain they are about this on NicoPedia.
It's a lot of work to separate entries, so I wouldn't do that unless absolutely sure that they are different people.
According to Nico Nico Pedia, Lamaze-P and Gojimaji-P are two different people. [This](http://lovenormal.com/replay/) suggests the same thing
Track 3 sounds pretty much like Miku, but of course can't be 100% certain...
According to the video description it seems like "flower" is a new VOCALOID that HoneyWorks got to test out.
