The Disney store is going have more SW promos, starting September 27th:
Disney Store SW Rebels Cards
Wish I had a Disney store nearby.

The UK stores have confirmed a set aswell.

It appears from the photo RedFive linked to, it is talking about the set from the UK, not the USA. I went to the Disney store yesterday, and as usual, the staff there knows nothing about another release of in-store Star Wars cards.
But I hope it happens.

Since my nearest Disney Store is up in Massachusetts, and 45 minutes from me, I opted to call before driving up there. And I lucked out with the young woman I talked to, because she was a plethora of Star Wars trading cards information, but unfortunately, there is nothing new {after the series 2 / Empire sets}. And she said that calling every few weeks wouldn't hurt either.

The UK set will be 12 cards released 3 cards per week for 4 weeks starting on September 27th.

There will also be a newspaper tie in with the Daily Mirror presumably on the same day.

We may be getting them as well in the USA. Disney is hosting a 2 day event for the show in OCT. The same weekend as NYCC.

I just read the show has already been renewed for another year, plus they are going to re-air the debut episode on the main ABC network and it will feature a bonus scene with Darth Vader voiced by James Earl Jones himself. Pretty cool!
