Define "competitive"? You dont generally keep up with a platform that is breaking all records.
You dont have to be vying for 1st place to be competitive. As long as you maintain a reasonable percentage of marketshare, your platform will continue to get support and will thus continue to sell when it becomes more affordable. It also has nothing to do with how powerful or weak a console is, so Im not sure at all why you put that little dig in. As long as the systems continue to get the same games, the general consumer wont give a shit - See the 360/PS3 split.
Xbox One has plenty of games left to push it in the coming Months. To cut it by $150 at this point would be brand suicide in terms of consumer trust. Theyre relying on value bundles which is the better bet than huge panic cuts. It helps them lower that bar for profitability while continuing to show value... And yeah, its a lot of value thanks to Kinect.
Expect small cuts in key markets (UK already has it) and continued value bundles. Kinect Sports will be next up, likely accompanied with a US pricecut similar to the UK/Titanfall cut.
The early days are all about legs. Maintain the legs, build the userbase, support will continue. Thats what theyre doing in Western markets.
