Help Please MacBook Pro Retina

Hi I am student and my birthday is soon and I was wandering if I should buy a MacBook 13in Retina display now or wait until June when supposedly Apple will update their Macbook line? I would say yes to go ahead and buy it but I have heard from sites like MacRumors that Apple could have design change but yet I have also heard rumors that in will only an internal upgrade. So I am asking you people of the tech world what should I do?

Here is a link to both of the articles I mentioned above

The one that metions a design change refer to MacBook Pro section

The one that mentions only internal upgrades
