Just checked on the OWI Twitter, and apparently Lorne appeared on "Giant Bomb" yesterday.
He pops up at around 1:15:50 in this video:

Lorne states the reason they're secretly showing Soulstorm because "They're ahead of where they thought they'd be" and it's working and running, and they wanted to show it off this year.
He also told a story about the infamous Munch PS2 footage, and for the first time on public record admitted it wasn't actually created on a PS2 dev kit. One of their new partners were going to cut OWI's budget, so he came up with a workaround. No publishers were allowed to show PS2 footage, so they just used the assets in 3D Studio Max and called it "visualisations" and it got lots of coverage as some of the first PS2 footage, and it stopped their partner cutting their budget. (Basically)
That's pretty much the only Oddworld info Lorne talked about. He didn't really speak all that much, and barely at all about Soulstorm.
