Portal Denied XBLA Release: This Was A Failure...

I'm making an note here: HUGE REJECTION. Software developer Valve recently sought release of their title Portal on XBLA. What was Microsoft's response, you might ask? No. Doug Lombardi, marketing director at Valve commented:
We'd love to do that. Right now it's something we'd love to do. I'd love to sell Portal on Xbox live. The platform holders aren't doing that right now. There's a size limit and all kinds of other things.
Microsoft currently sets the limit of XBLA releases to 150mb, fairly large considering how small the standard premium drive is a mere 20GB. Portal weighs in at over 500MB on it's Steam release. It is unlikely that they will be able to scale back the size, considering the sheer weight of the game.
Personally, I'm rooting for Valve. Mission packs as DLC would be fantastic, however unlikely. I guess we will have to stick to playing the game as a piece of The Orange Box as it stands.

Why does it have to be an arcade game? They've got xbox originals on there, and you can download the entire tomb raider: anniversary game too, right?
I for one have loads more than 150MB of free hard drive space. Why is Microsoft so insistent that I haven't?!

Xbox origionals is games that were origionally on the Xbox
If they really want to make a point to Microsoft to up the file size limit they should release it on the PSN store or something.
But, then again, I'm not sure if they actually realize how big you can make those games on PSN.
I'm making a note here. Not "an" note.
