Yes.. it is..
Did you miss the part where he went to the settings menu and showed the OS version?
And word, there was clearly a game demo (Mansion Demo) on there, why the hell didn't he go to it instead of just going through the same screens over and over again?
thats not Gingerbread framework or UI... and when has Google ever used the codenames for the OS version? never
If it were Gingerbread the framework wouldve been the black and green that Google's already shown and it wouldve said 2.3, not gingerbread
