Panels 2: will be released for 6 in a couple of months
Views 2: only for Drupal 6.

Panels 2

Lets you create nodes that contain regions (panel-nodes). Considerably more flexible than the original panels.

Can disable Drupal blocks regions with Panels 2. This would be very nice for landing pages where you want to eliminate the side navigation.

Views 2

Very stable even though it is still labeled beta.

Views 2 can work with nodes or other content types like users.

Ok, this is pretty cool.
