Okay, this isn't specifically about a new theme but a new club. The club is from Shape5 and launches on May 1st 2007.
Now, you can't buy anything yet but they are promising the launch will come with some free themes for Joomla as well 'several' other items.
The first 200 members will get a 20% saving (although we don't know what the price of membership is yet) and for those that sign-up for the newsletter there is a chance to win free membership. Now, because we've not seen anything we can't comment so it's just a little bit of promotion for the new themes club.
Go visit Shape% here for more information but rest assured on May 1st 2007 we'll review everything they're offering.
