Whatever the case, there is more gamer hate towards Kinect than Move from what I've seen. I believe it comes from how much more forcefully MS has pushed it, both in terms of marketing and as a core component of the Xbox brand and games.
As far as the companies strategies being the same, that is doubtful. MS is a software company first and foremost, with a couple of hardware offerings. Sony is a hardware company first and foremost with financial service wing and an entertainment production wing.
I'm guessing MS will want to use the Xbox brand synergistically with their other software platforms (phone, tablet, desktop) in order to create and strengthen their ecosystem, hopefully locking in users the same way apple does.
Sony looks to be going a more traditional "sell hardware, make royalties" route, with added revenue from digital services like movie rentals. I don't see any evidence of Sony trying to create an apple-like lockin ecosystem or a multiplatform software environment (phone/tablet/desktop). Maybe that is their goal, it just doesn't look like it from the outside.
I'm strictly addressing your completely false statement that Sony didn't try to integrate Move into a bunch of games and that the 1st party didn't develop the same or even more than MS.
Again, in regards to this topic, both Sony and MS tried to expand their core audience by going after the Motion Control audience that Nintendo owned exclusively.
MS was clearly more successful, but Sony still had a big marketing push for Move. i can't even count how much i saw that Keven butler commercial at the height of that marketing campaign. In fact, I saw that ad, more than anything I remotely saw for Kinect.
Next gen it's the same strategies as well.
MS is rumored to include the Kinect 2.0 with the Nextbox and Sony is rumored to be including PS Eye 2.0 with the PS4.
Sony promoted the new capabilities and and Media Molecule show of their new Move game and MS will surely show off Kinect 2.0 and it's games as well.
Again, just like this gen, both companies have the same strategies in regards to motion controls.
