Your Blizzard poster (known as Karune):
Please read trough your "sources".As mentioned before, players will be able to use Battle.net for free when they purchase the full version of StarCraft II. There have been no changes to this.
Edit (another post from him)
Why should it mean that it will be a "not full version"? There are always demos and stuff, wich might get lucky enough to be able to get an online trial on (an own system for demoes as an example) << I dont comfirm that at all.lol- here is one simple scenario:
When you buy StarCraft II from the store, you will be able to play on Battle.net for free. This is not a temporary trial of Battle.net.
Not purchasing the full version would include any illegal method of attaining software. In that case, you would not be able to get on Battle.net.
I would mean that they posted something simlular on all their software.
