I reckon I can wait.

We really need more data. Now the zillion dollar question, do we send MSL back to the same Meridiani (more or less) where we know we have all these interesting features, or do we send it to somewhere new on Mars that we've never visited before that will also maybe tell us something new, but might NOT have the right features.

My bet at this point is that there will be a fierce debate with proponents either side but eventually it will settle on a different bit of Meridiani to "ghuarantee" we get the right geology, while trying to add a touch of variety (and at the same time giving us a bit of an areal perspective across Meridiani with two sites visited).

Mars needs Data.

Well, it doesn't, but we Humans do!
