There was an interesting Wall Street Journal article in June about Disney Jr shows and the decisions around merchandising. It made it sound like Sheriff Callie stuff may not be forthcoming, which would be too bad because my daughter loves that show too.
Here's the relevant quote, though if you google wall st journal and disney jr you should be able to find the whole story:
"Sales have consistently grown, Mr. Chapek said, in part because after taking over the consumer-products unit in 2011 he reorganized it to dedicate staffers to each of the company's key brands including Marvel, the Muppets and Junior. Previously, Disney Consumer Products was organized by product line, such as clothing, toys and furniture, and older brands faded in favor of the new.
In some cases, his unit has passed on the opportunity to immediately sell products for Disney Junior shows that don't appear to have much toy appeal, such as the recently launched "Sheriff Callie's Wild West" and "Henry Hugglemonster."
