After Major Revision what is the decision?
The status is "under review" because the editor decided to ask the reviewers to look at the paper again. Since there's no way to tell what the reviewers are going to say, there's also no way to tell what decision you can expect, either. The fact that the initial reviews were favourable means there's a good chance your paper will be accepted, but reviewers can change their minds, and there's no way to be sure.
