The "spaces" that come with Home are...well, they're fairly basic. The service's real potential lies in spaces that can do more, like the Warhawk Command Centre. Thankfully, lots more new spaces are on their way.
Sony's US director of PlayStation Home, Jack Buser, says "you'll see about three new spaces launched a month - I'll be shocked if we ever go under that number, we have so much in the pipeline". Good to hear, especially when he adds that these new spaces (which take around four months to develop) will be using "new technology" that we've yet to see.
Hopefully that means new interactive stuff, like Warhawk's sand table, and not just new ways of cramming advertising down your craw.
