It's not a new theme from Joomlashack, yet that is, but a brand new site design and a much easier way, if they don't mind me saying, at viewing and getting at the themes.
I'm not sure why they've changed but it is better. The layout of the site is much better and pretty much everything you need or would like to get to has been well categorised in the menu system at the top.
Everything is as you'd expect from Joomlashack they've just made it better and well, I thought I'd point you in the right direction if you haven't already found them.
