The dictionary defines a gimmick as:
1 a : a mechanical device for secretly and dishonestly controlling gambling apparatus b : an ingenious or novel mechanical device : gadget
2 a : an important feature that is not immediately apparent : catch b : an ingenious and usually new scheme or angle c : a trick or device used to attract business or attention
I am a bit confused. Let's see what wikipedia has to say on the matter:
In marketing language, a gimmick is a quirky feature that distinguishes a product or service without adding any obvious function or value. Thus, a gimmick sells solely on the basis of distinctiveness and may not appeal to the more savvy or shrewd customer.
I'll not sure what your angle is, but honestly. Motion control is quite clearly a gimmick. Until someone can apply it in a way where it has lasting appeal and can be applied to something more than basic sports controls or rail shooting, then there's no point. It's not truly innvoative, it's just pointless in most cases and it ceases to be fun very quickly. And it doesn't matter what company does it, the result will be the same.
So to answer the question in your topic title, A resounding
"NO!"
