The word on the street is that new cartridges are being released at the Winter CHA next week. I'm working on getting screenshots and as soon as I get those I will post them. The new cartridges are:
Sponge Bob Square Pants
Kitchen and Bath Decor
and a Stamping Kit W/Cartridge.
Being ProvoCraft isn't exactly known for their promptness all I can say is....we'll see. ;)
