"It has a lot of heart" That's a new one.
Anyway i enjoyed Spiderman enough, so i'm looking forward to play this eventually, but i'm not sure it justifies 500€ of console.
Not a lot of ways to describe an expansion that's going to likely be the same game with an xmas setting, 60fps and some graphical touches, and a new story campaign and some new side missions.
I've been to NYC at xmas and it's pretty awesome, so that's actually a real good modified city as they can go all out with decorations and lights to show off the visuals. And like you said, the main game is good, so more of the same is fine.
But I'm not expecting anything beyond more of the same here.
Though most launch titles suck across the board for every system, so more of the same is probably still gonna rank high for launch games. Too bad they killed Psygnosis and we don't get a new Wipeout at launch.
