Just looking at the uisounds folder on the iPad tells me the next gen iPad will be great, unless this is all just very generic & part of the next iphone/ipad update:
- begin_record
- begin_video_record
- end_record
- end_video_record
- jbl_ambiguous
- jbl_begin
- jbl_cancel
- jbl_confirm
- jbl_no_match
- middle_9_short_double_low
- photoShutter
- shake

These are all new sound within that folder on the iPad. I wonder what's coming...
