It's May, I'm sick, but I'm still determined to keep updating this list. As usual, it is focused on the North American market, with sections for Europe and Japan exclusive titles in their own sections below.

Last month was pretty big, with Soul Sacrifice landing at retail, and a bunch of big downloadable titles launching on PSN. This month is a bit more sparse - there are actually no fully confirmed Vita releases for May yet, though Futurlab's acclaimed shoot 'em up Velocity Ultra, twitchy murderous rampage sim Hotline Miami, charming puzzle adventure Jacob Jones and the Bigfoot Mystery, and puzzler Quell Memento are expected to make an appearance. Parts of Europe also just got Farming Simulator 2012, though no word on whether the rest of the world will.

April turned out a solid number of new announcements. Retail-wise, the Jak & Daxter HD Collection is getting a Vita port in June, metroidvania Batman: Arkham Origins Blackgate is coming, Sony is relaunching the successful PSP Invizimals franchise with Invizimals: The Alliance, and Ragnarok Odyssey is getting an expanded rerelease which was announced for a western release right off the bat.

PSN got a good amount of love too. Puzzle platformer Stealth Bastard was announced with remade 2.5D graphics and a new name Stealth Inc. - A Clone in the Dark, Llama enthusiast Jeff Minter revealed Tempest remake TxK, plus a bunch of other indies like Cloudberry Kingdom, OMG HD Zombies, 1001 Spikes, and Kung Fu Rabbit are also coming.

In Japan, outside he previously mentioned Ragnarok Odyssey Ace, the notable announcement was a Vita exclusive Corpse Party sequel.

And, I'm done. On to the actual list:
