The longer in the gen the less important it is

both playstation 4 and Xbox One were a long LONG way from complete software wise when they released, think it is fare to say they were both beta on release. both barely had the basics working let alone the time to be working on the nice to haves, So I imagine BC was something both Sony and MS would have liked from the start but there really is only so much you can complete in a given timeframe, especially when you need the underlying OS complete before you can think of emulating something on top of it.

Yes, it's a great feature. My friend who never owned a 360 bought Geow Ultimate because 1-judgement would be free with the game. BC is what pushed him to buy it, so to say it doesn't effect sales is wrong. When BC fully releases this holiday you can bet we will be playing Gears of war 3 together.

its just a choice for upgrading from previous gen owners when their old console die ( provided their games already available for the new sysytem ) if they are people who not so interested in new gen games, but it will only be a extra feature for people who more interested in new gen games...

 That's how PS3 and 360 started out. You're right, but that doesn't explain why MS doesn't outright give full BC to the console.  

you sure? he plays a wii game on his wiiu.

By the sounds of it, FULL BC compatibility is their intention, at least as close to it as they can get. so not sure what you are stating there. Whether they achieve it or not is another matter as it isn't an easy task when you have such a massive shift in underlying architecture. I hope for the sake of my old games they do get there.

I don't think backwards compatibility is over hyped at all, honestly.

It's a really useful feature, and I've used it quite a few times with my Wii U. Sure, it's not the ultimate sales driver but it does increase the value of any console in my book (including the XBO).

According to the minute long roaring applause at Microsoft's press conference, its a big deal. And definitely not overhyped.

Backwards compatibility is really only an issue for people who've been gaming longer than this generation and care about playing those games, and threw away there old systems, so its fairly niche. MS also brings a lot of their games to PC so its not really that much of a benefit, especially when older games on a newer console vs PC is skewed in PC's favor.

Especially when you consider the number and subset of games for backwards compatibility vs being on PC. It really doesn't do much for the question, why get an X1 if I have a PC. In contrast, I really want to play Melee since I've been out of of my dorm, and I defo can't play Splatoon or Smash 4 on PC.
