Sorry OP, but there's no way to spin it... XB1 is NOT doing well right now. It has outsold X360 in the same time frame, but that's because of the non-supply constrained launch. Take away 2013 and the XB1 is tracking WELL below X360.
That's not to say that it will be a failure. With some more aggressive pricing and some more AAA titles like Halo, it will get back on track. But taking 1st place this generation is pretty much impossible. Let me explain why.
1. They no longer have an edge in terms of BOM (bill of materials) and therefore they no longer have the edge in terms of pricing.
2. They don't have the worldwide appeal Sony has, so a comeback like the PS3 is out of the question. The PS4 is outselling the XB1 in PAL regions by more than 4:1. There's no coming back from that.
At best, MS can take their home turf back and have moderate success. But the PS4 is taking this generation with ease.
Is XB1 doing well right now? No. Will it sell as many as X360? Possibly but unlikely. I think it will sell 50-60M lifetime. I can see the PS4 selling 100-110M lifetime.
