I was wondering if there was any plan for ArcGIS to support MrSid generation 4 for read. I understand creating MrSid is no longer a thing in ArcGIS. MrSid gen 4 seams to have neat things regarding multi-band images. Lizard tech has a 3D analyst plug-in for 9.3 but they only mention terrain data. I was wondering if there was any word on support of MrSid Gen4 in Arcmap without 3D analyst just to view the images.
Esri has this enhancement request documented under NIM063903: Provide support for MrSID Generation 4 (MG4). The implementation of the request is being targeted for the 10.1 release.
