Xbox's backtracking doesn't seem to have had much effect.
I'm willing to consider purchasing an Xbox One now, having all but completely written it off in the aftermath of E3, but my preference still lays with the PS4. All other things being equal, Sony still did the right thing with their DRM policies and forced MS into doing the same, and I feel they deserve my custom for that. The PS4 allegedly being more powerful and cheaper is icing on the cake.
Oh, and they don't put Netflix/Youtube/the rest of the internet behind a paywall like MS do, and that is a decently sized factor for me when choosing my next-gen console.
