Phils responds is just bullshit to me.
I can even understand that you don't want to be the place that gets every indie title much later than your competitor. However this happening has simple reasons that MS just fails to acknowledge. Instead they just pull out the asshole card and say that if you don't release on our platform first/at the same time, chances are your title won't come to our console ever.
This is exactly the "spirit" I loathe from MS, instead of funding their own IPs/studios they decide to buy exclusivity like in the Tomb Raider case, essentially taking something away instead of adding something to the market. Instead of giving indies an incentive to release in a timely manner on their platform they rather prevent the title from getting released at all if they do not follow the way MS wants.
It's really like MS has not realized that they are quite behind the console race, and they are loosing ground every day. This is not 2008 anymore where they were leading by a lot and could dictate how indies come to their platform. You know ... instead of wasting millions on a stupid Tomb Raider deal they could have used that money to support indies, fund games, help with certification or any other needs small studios have. Give people a real reason to actually consider your platform as viable.
Imho every game not released on your platform means that someone might decide against your console, or if he already own it it's a reason to buy your competitors product.
