Two days ago Adobe confirmed in tweet that Lightroom 7 will be announced by the end of the year. I was able to capture a screenshot before the tweet got deleted:
The rumored Adobe Lightroom 7 will probably be announced during the Adobe Max conference (October 18-20, 2017).
The current Adobe CC plan rates can be found here. You can get a free Lightroom trial on this page. The last three versions of Lightroom can be downloaded here (see also this link for more information). Adobe's website has also a dedicated page for Lightroom CC.
