For anyone interested in version 4:

I remembered today that there is a Rosetta Stone Kiosk on the ground floor of the building I work in. I went today to ask about version 4 and got some new information. The three new features are Rosetta Studio, Rosetta World and the Mobile Companion.

The Mobile Companion is an app for your iPod Touch or iPhone. Its a review of what you learned on your computer and using it doesn't affect your lessons.

Rosetta World is an online interactive game site. You can go online and play games by yourself or with other people who are learning the same language as you. A third option that wouldn't be easy to find for the case of Irish is to find a native speaker of the language you are learning that is learning your native language, a language swap. The game that I saw had two views of a room and in the room there were different objects. Both users saw a different room. In the language you are learning either by typing or speaking you have to describe your room to the other person who would then change their room until both rooms matched. Hopefully this is understandable because its difficult for me to describe. An example would be a bike in each room one blue and one red. You would tell the other person the bike is blue and they would change it from red to blue.

Rosetta Studio is an online live session that you unlock after completely different lessons. You are shown a time table of available times that a native speaker is available and you schedule when you want to meet with them. The salesman's example was while he was learning Mandarin the native speaker could tell him how to adjust his jaw to fix the pronunciation of a certain word.

Seeing as I am a native English speaker learning Irish, finding a language swap obviously wouldn't be possible. Also, he mentioned that the Rosetta Stone staff is currently learning Irish and other less known languages to help staff the online sessions with a "native" speaker.

Also these features are $50 to upgrade from version 3 and include a 3 month free subscription that is $9.99/month after the initial 3 months.

It definately would be more advantageous for learning a majority language but the price isn't too bad so I will probably give it a whirl...
