This is a sign that the modular IOS won't be the way in the future
for IOS on Catalyst 6500. With the new Supervisor the IOS-XE high
availability model is going to be used (however it is still to early
to get into gory details), so rather than going deep down to the
sub-process level patchability which was the target for the modular
IOS (and it seems it wasn't widely used), 6500 with the classical IOS
is going back to the developments Cisco made to its NSF/SSO and ISSU
features. Also, that way, IOS code base for the 6500 will benefit the
most from the code already written and present for other platforms.

Until there's formal CCO statement of direction, You should contact
your account team to get more details.
