Its a pity for me as I would love to have Foreplay/Longtime in my RB2/3 collection.
Profile shows he's on the 360; he's all good for export.
By the way, the way to get songs off your other RB game discs (exporting) has an info page here: http://www.rockband.com/support/export-rock-band
my thoughts on the subject are documented in other threads. If they are doing it for blitz I am of the opinion they should do it for the other titles too. There are a lot of tracks that would benefit from an RB3 upgrade, granted that comes as an expense to HMX.
If people don't have export codes or can't find new copies of those titles then there are Blitz goals that they would be unable to complete or contribute to. To me it makes sense to make these tracks more accessible to a newer audience.
So, still no way to export RB to RB3 on Wii?
