I love the 2013 MBA I'm planning to buy it but I heard that the new model is coming in WWDC this year.Is it just a rumor or it's confirmed by Apple.If it a rumor is it 100%? And if the new model comes out, it will be the little update or huge update? I don't want the retina display but if it's lighter and thinner I would wait for it.If it just a little update or it won't come out, I'll buy the 2013 model. Or can I wait for the new one to come out and buy the old one to save money?(I don't have a lot of money to spend and this going to be my first and only Mac for years).
