I thought Nintendo said all games they make will support Dolby Pro Logic II (and progessive scan)? IGN says in there review that it seems to not support DPLII, which is interesting.
But I wasn't expecting to get this anyways. Double Dash is only a month or so away. Also to note, this is Nintendo's first game to support LAN. Hopefully future games do better with LAN, mainly Double Dash

(then PSOIII

)
