I wait to do these until the PSN Store updates, because that's usually more interesting than the store releases. Even more so when there's no releases. There just hasn't been a PSN Store update this week either. The PS+ preview post refers to one happening on 12/31, but it doesn't appear to have happened.
That preview post does mention Urban Trial Freestyle will be free for Vita whenever it goes up, and Contrast and Grid will be off of PS+ on 01/07. I don't think I ever downloaded Contrast, but that was harshly reviewed game from the PS4 launch. (That also means PS4 "Don’t Starve" and one of the PS3 January games will drop that week, as they seem to be sticking to the same number of games available at all times.)
The most gaming I've done is playing Pocket League Story 2, and mostly trying to figure out how we missed the entire E level. (Hooray for FAQs.) I got FIFA for New Year's Day and hopefully will find some time for it.
