Kotaku's live blogging the conference with Ueda.
Some tidbits about the collection:
Improved textures
Brushed up art assets (HUD, etc. I assume)
Locked 30fps for SotC (the framerate he Ueda designed it for, apparently)
Ueda's concerned abotu the NA Ico boxart, and "will be lookign into it" lol
Stereoscopic 3D support
I'm glad that this project is being handled by Team ICO. The God of War ports were done by some random third party, and were pretty half-assed, featuring a horribly stretched HUD, SD FMVs, and other issues. This collection is rightfully getting the love it deserves!
Here's an example of how the remastered version of Ico will compare to the original:
