It won't get versions of high selling third party home console games because of any or all of the following;
1. Wrong architecture making conversions more difficult and costly
2. Low performance level
3. Poor controller
4. limited storage either on cartridge or in tablet
5. wrong userbase
6. Small userbase
7. Poor online infrastructure
8. Publishers desire for the NX to fail
9. Developers wanting to program high performance hardware not lower performance hardware
10. Retailer apathy
Even if the product has haptic feedback and the controllers have built in colour displays that makes the tablet very futuristic and attractive there is still the huge issue that its hardware performance level is not competitive and once you've got over the novelty value you are left with a limited product and a small number of games. I can imagine the controllers being absolutely terrible due to shape and limited analogue controllers etc.
Again I realise this is all speculation but the current signals about NX are terrible and really represent a withdrawal of Nintendo from the home console arena.
