What is the modern version of Cubase SL 2002 ??

What would Cubase SL 2002 be if you bought it today and is there an upgrade?

Thanks in advance.

I’m assuming that you mean what would it be equivalent to in terms of features.

According to wikipedia (http://en.wikipedia.org/wiki/Cubase) the SL level became the Studio level (at Cubase 4).
However, the studio level got merged (I believe) into the full version with Cubase 6.
So, therefore, an SL version today would be the full version.

The only upgrade available from SL is to Cubase 6.5 (full version), according to the Steinberg online shop.
