which edition of altera kits comprise

Hi ff113,

In a word - none. That example was designed to show how Nios fared with Stratix II when support came out with Quartus for those devices. If you install Nios II 1.01 you'll see a whole set of example designs & board components, all tested in hardware, for two real-life Stratix II dev boards. These are the Nios dev board S-II edition (2S60ES chip), and DSP dev board S-II edition (a faster speed grade 2S60ES chip). More Stratix II boards will likely follow in the future.

I am not involved with the production of either of these boards, but my guess is that they should be available for purchase soon, if not already.
