There will always be something new upcoming. All i know is my mini plays everything thrown at it from the app store without issue. Games look sweet, don't care about retina display, have an iphone 5 and the games look just as good on the mini ipad as they do on there ...
I want a Mini but I was disappointed by the dimmer colors of its screen. I know some people say they don't notice, but I noticed it immediately the first time I saw them. And sadly the retina version didn't improve the colors.
I'm hoping the Mini "3," or whatever they call it, will have nice vivid colors like the iPad Air (heck, or even like my old iPad 3 when I had it). Then I'll buy one.
OP - I think you should wait until we hear about the next iPad versions for 2014. Then like someone else said you can choose the new version or get an older version even cheaper.
iOS: iPad Air 2 128GB Space Gray, iPod Touch 5 32GB Space Gray
Android: Samsung Galaxy Note 4 Black/Gray
This is a good thread cuz I was thinking about the same thing. After reading all what you guys commented here, I think I will get iPad Mini Retina since I love retina display. I like simple and easy stuff.
