From all that I've heard, that's apparently the case. There was also an interim version where both Kara and Kal (in the person of Henry Cavill) appeared at the end, along with Keaton and Wonder Woman.
Unfortunately, the Cavill and Calle scene was cut. Thankfully, the Keaton part did not happen.
Another thing I'm not real clear on is why there would supposedly be "no Wonder Woman" in the timeline Barry creates. Diana is thousands of years old. Are we to assume that in this timeline Steve & the Germans never end up in Themyscira for some reason? Even so, if Zod's forces took over Earth, the Amazons would presumably have to fight eventually.
You can assume Wonder Woman would not appear because the reasons she left Themyscira did not occur in the Barry-altered timeline. Why would that series of events play out the same as in the prime timeline?
