According to an article, Janet will be performing in Buffalo on Tuesday, July 21. The article is from EXACTLY 1 year ago though. The date Tuesday, July 21 DOES match with this year though. Yesterday, a fan said on Facebook that Janet was scheduled to perform in Toronto, Canada in July.
If all this is true, it seems like she's heading on a US tour. NO WAY she's doing that without new music/an album. And it has gotta lead into a world tour (perhaps)...
we'll see...
