Checked... where? I managed to find リンク to Repo Man (which was the latest episode).
But, to answer your question, as of right now, the 表示する isn't cancelled. It hasn't been renewed for an eighth season, but the CW says it's relatively safe.
The last episode was Repo Man aired on 17th Feb. After that all the CW shows are having a season break. So after the break ends, the 次 epi of スーパーナチュラル will telecast on 16th March... Till then we've to wait and countdown!! ;)
