Spent some time this last week and looked over all of the modules for Drupal 5. What was interesting is that 99.5% have not yet been updated to Drupal 6.

IMO it will take months and in some cases a year before all modules are fully compatible with Drupal 6. Some will never be updated and will just go away for lack of support, etc. Noticed that Drupal 6.1 is now out......

Perhaps someone else has a better insight on this scenario.
