Looking to get a handheld system, is the Vita still worth it? I also have an iPad mini, and an iPhone 6. If I get a Vita now, are they releasing a new model soon? If you didn't have one right now, would you still get one?

Self explanatory. Just looking for some purchase advice. Should I keep plaint iOS games, or expand into the Vita universe? :)

edit: Thanks for all the info guys! I like this community already. You're all very helpful. Since I'm learning to speak Japanese, and want to play jrpg's, I'm definitely going with the Vita. Now I need to find one at a good price, or a used one in good condition! 👍🏻
