Microsoft's Phil Spencer talks Xbox exclusives having "quality and impact"

Microsoft's Spencer on stage at Xbox 2011's Electronic Entertainment Expo keynote presentation.
For the duration of 2011, many Xbox 360 owners bemoaned the lack of system-exclusive original games coming out of Microsoft in a gaming landscape that has been quickly become increasingly less populated by third-party exclusives. And in an interview with Game Informer's Matt Helgeson (Issue 226, February 2012), corporate VP of Microsoft Game Studios Phil Spencer addressed the difficulty of creating "core IP" like Gears of War and Alan Wake in response to Helgeston's question about whether "establishing new IPs in the traditional, triple-A console space" was a priority for Microsoft?
"I do think that it's [about] quality and impact, not number of releases in a year," Spencer responds as a follow-up to describing the process of creating core IP as anything but easy. "I went thorugh the process of creating Gears with Epic and I know the sweat, time, and effort that went into it."
But despite the difficulties, Spencer mentions that Microsoft will continue to "focus on [building new IPs] with partners like Crytek and new people that aren't announced yet." How many are expected to debut or be announced in 2012 is still not known.
Game Informer's Helgeston also broaches the topic of HD releases and collections — something he believes "Sony has done a great job" with — and if the November 2011 release of Halo: Combat Evolved Anniversary was a signal of more HD remakes to come from Microsoft. Spencer says no, "Halo Anniversary wasn't created with that in mind." He continues in the interview, "It was more a celebration. It wasn't the beginning of an HD remake line. I [don't] want to get into a world where people felt like I was just trying to sell them things that they've already played."
What do you think? Would you want more HD remakes of original Xbox or older Xbox 360 games? And what's your thoughts on new IPs on Xbox? Would you rather more original titles or existing titles become Xbox exclusive?
