In a US blog post, SCEA marketing boss Peter Dille has outlined what we can expect from Sony in terms of services for the coming year.
A "big reason 2008 will be a great year for PS3 fans is due to the big things we have in store this year for the PlayStation Network," he said. "The PlayStation Store redesign is the first step but it’s only one example. Our primary goal with PlayStation Network is to form an evolving entertainment network where the PlayStation community can gather and discover new forms of entertainment."
Dille also promised that in-game XMB would hit in 2008.
"Community-related services available via PlayStation Network have also been a big focus for enhancements here in 2008," he said. "We know you want in-game access to XMB features and we’re committed to bringing that, among other community-related services this year. They will be designed to allow more community development and collaborative gameplay, as well as recognize and reward you for your gameplay accomplishments across a broad portfolio of PS3 games.
"Of course, 2008 will also see the launch of PlayStation Home, and we’ll have more announcements on the expanding community functions within PlayStation Network in the near future, so stay tuned."
The four corner-stones of PSN's 2008 are "the PlayStation community; free online gaming; digital media download services; and original content," apparently.
