Actually it is tracking WELL below the 360 now. It was only "ahead" of the 360 based on the strength of it's launch late last year. THIS year, it's well below what the 360 was doing. I also wouldn't call being outsold in Germany by a 4:1 ratio "doing well"...or 3:1 in the UK. Heck, it can't even beat out the PS4 on it's home turf (North America)!
I think you also have too much faith in the software coming out this fall. The only title of any significance is Halo MCC. Nothing else is even relevant.
