At last check, they were pushing for the OS to offer a choice of browsers at install time, including IE. I don't know if thats the route MS will go with though.
But as some people already said, this has quite a bit difficulties when actually implemented. A simple problem would be, which browsers should be selected? Who should decide which browsers to be presented at install time?
This is already a non-problem for computer vendors, because if they desire they can already put any browser they wanted into the computers they sell. Of course, as we know that almost no vendors bother with this because this just increase their support cost.
Since Microsoft decided to provide upgrade prices for all Windows 7 without IE, I think this is probably already the best for EU consumers, at least practically. Heck, consumers elsewhere don't even have this option. I'd be happy to buy a cheaper Windows without IE, because I rarely use IE anyway.
