Most of the pictures on the site show the keyboard with Mac layouts, and they've specifically said it'll be cross-platform. It's fairly obvious that the people working at that studio are Mac users. I think it's safe to say that it will definitely be Mac compatible. Anyway, I'm quite interested in the Optimus full-size keyboard, assuming it's "less than a good mobile phone" or around $300. $100 for the 3-key mini keyboard is just too expensive for me.
