PLANTS VS. ZOMBIES 2: IT'S ABOUT TIME is out NOW, worldwide on iOS and Android. It's a F2P title with IAP's, but PopCap claims that the microtransactions are not necessary to beat the game.
PVZ2 will release on other platforms, but dates and distribution methods have not been announced.
I don't feel like writing any more so here's a WIKI link detailing all the important stuff.
OFFICIAL TRAILER:
GAMEPLAY WALKTHROUGH:
WHAT'S NEW: (copied and pasted from iTunes)
The zombies are coming… back. It’s about time! The sequel to the hit action-strategy adventure with over 30 Game of the Year awards is here. Join Crazy Dave on a crazy adventure where you’ll meet, greet and defeat legions of zombies from the dawn of time to the end of days. Amass an army of powerful new plants, super charge them with Plant Food and power up your defenses with amazing new ways to protect your brain.
NEW PLANTS! NEW ZOMBIES!:
Meet Bonk Choy, Bloomerang and Lightning Reed: Just a few of the powerful new plants that will defend your lawn through time. Go toe-to-missing-toe with dozens of new zombies including Ra Zombie in Ancient Egypt, Swashbuckler Zombie on the Pirate Seas, or Chicken Wrangler Zombie in the Wild West. In every new world, clever new zombies and brain-teasing challenges will test your zombie-zapping skills.
AMAZING NEW WAYS TO PROTECT YOUR BRAIN:
New Plant Food and power-ups will take your game to new dimensions. Plant Food will supercharge your plants when you need it most. Use your fingers to pinch, flick and zap zombies off your lawn.
LOOK OUT! ZOMBIE CHICKENS!:
Seriously.
NEW LEVELS OF EXCITEMENT:
Battle the fun-dead on land, on sea and… on the rails? Unlock ultra-challenging (and ultra-fun) endless levels — Pyramid of Doom, Pirate's Booty and the Big Bad Butte.
THE FUN NEVER DIES:
Gather keys to unlock brain teasers and new plants. Collect coins to purchase potent power-ups. Earn stars to take you to new worlds. Survive long enough and you'll be rewarded with piles of prizes and achievements. And that's just the beginning! The future holds many mysteries. Also, zombies. Lots and lots of zombies.
