This is by no
means conclusive, but there's a Tron Uprising fanpage on Facebook that recently posted the following message:
|TRON Uprising. SEASON 2 TRAILER COMING OUT THIS DECEMBER
info from: Disney
Given some of the other posts made by the owner of this page, it seems likely that this is someone who might see a slight hint of maybe something happening and take it as a confirmation. The owner of the page later posted this video, saying that it was proof of a season 2 trailer, despite the video clearly stating the contrary:
Probably nothing, but I figured I'd mention it. He may actually have a source that he's not willing to share with anyone, but he did say that his source was Disney X-D. I've done a few brief searches, but was unable to find any evidence of a season 2 trailer announcement. What I find odd is that he says a trailer is being shown in December, neither of which are even remotely suggested by the video.
For those who are unable to watch the video, all it says is that Bruce Boxleitner mentioned at Wondercon that Disney likes the idea of a second season for Uprising, but has no plans at the moment.
If anyone can find a statement from Disney X-D, do share.
EDIT: For clarification's sake, the mentioned Facebook page is NOT an official page owned by Disney. It is a fan-run page, despite the misleading URL: https://www.facebook.com/TRONUPRISINGOFFICIAL
