Different versions of logic studio?

Hi people! It's my first time posting here.

I have a question to ask. You see, I bought the logic express just before the logic pro standalone version was released and I feel like I had been sucker punched hard in the guts. I'm looking to upgrade my logic express from the prev apple offerings of upgrading to logic studio. I've looked at eBay and amazon for the upgradable logic studio but I'm seeing logic studio v2.0 and logic studio

My question is which is the latest version offered before the standalone logic pro was announced? Or is there even such thing as an apple logic studio 2? I've compared the specs and both seemed to be offering the same specs and etc.

Anyone has got any other idea for upgrading logic express to the latest studio?

Thanks !
