as far as we all know it should be the exact same thing you get on June 4th. Unless sprint throws something in at the lat minute. U may actually get an extra 2gb sd card with the google i/o Evo. They gave it out with about 200 songs preloaded on it

 

please use search function. it's been discussed many times

 

I'm really not sure if the packaging/extras will be any different, but the evo comes with the basics, including a complimentary 2gb card with music on it(may or may not be on the june 4 phones). The seller who sold me mine on ebay gave me 2 of the micro sd music cards...not sure if he grabbed an extra. The box is really tiny though, almost suprisingly so

 

EVOlution is right. But I also purchased one through ebay and was worried. Everyone says it should be the same exact thing. Hopefully I get mine before it even comes out. Good luck
