It is shocking that they could be doing a very unexpected movie with a black Superman but I think ultimately we can't judge it until we see it.
I am thinking if they go the Calvin Ellis route, basically Obama as Superman - that's a pretty exciting concept that's going to engage and excite a lot of people.
Another piece of evidence I think supporting this is that the WB allowed the Superman and Lois series to go forward. If they were going to do more traditional Superman movies I think they'd be less likely to let that series air.
And I think it's exciting and great that we're getting a new movie and the series at the same time, whatever direction they take.
