A moderator on the official boards has recently responded to a question about if there are plans for additional dates to be added to the tour in the US after the last show in NYC in November.
The response was "Don't know about additional US dates at the moment, but there are some international dates coming."
This information matches up with a question a fan directly asked Josh after the Newark show. The fan who had traveled from Australia, asked when he would be touring down under. He in turn asked Dennis and who replied December, to which she then double checked and asked if he meant December THIS YEAR! Josh then smiled and said YES!
So it looks like Josh might be escaping winter to grab some sunshine in the Southern Hemisphere in December. Last time Josh toured Australia was for the 2007 "Awake Tour". Dates on this tour included 4 nights at the Sydney Opera House, 3 nights at Hamer Hall in Melbourne, 2 nights at QPAC in Brisbane and 1 night each in Adelaide and Perth.
If Josh does tour in December, I wonder if he'll do Carols in the Domain again this year???
