Will the differences be radically different between the various versions, will it be like a deluxe version I.E more features if so will we be able to upgrade the current version to all other versions or will it be three completely self contained versions with not all features working in all versions.i understand that tcas etc may be included in the new versions will this then be enabled in the current version?Thanks

Adrian,As I understand it every item that is included in the forthcoming releases and that is availible in the already released series will be interchangeable i.e. TCAS and dual EICAS displays to mention a few.Regards,
