Chris Norden, Senior Staff Developer Support Engineer at SCEA has confirmed that all PS Vita releases will be available day and date on PSN with the retail releases. He also confirmed that there will be a 20 megabyte download restriction on the 3G model, similar to smartphones, but there will be no download restriction over Wi-Fi.

When asked about free-to-play games, he responded, “You are free to explore whatever business model you want. You’ll have to talk to your account manager, and say, ‘Here’s my idea, and here’s what I wanna do,’ but yes, you’re allowed to do that.”
