Zen Pinball 2 and Pinball Arcade both seem to be coming to PSN this week, which is awesome. Of course in a sense they're just basic ports and it will be interesting to see what, if any, improvements they have. Pinball Arcade apparently supports mostly real-time lighting now, and that looks much better. I haven't seen yet if/what the upgrades are to the Zen Pinball 2 tables, but there are likely to be some, as there's a smaller number of tables initially available (though you never know, could be licencing as well - they have a good reputation for pushing hardware and features though, with 3D support on the PS3 version)
