I would not take that positively.
If it was going to be the same thing as the console version, there would be nothing to hide. Being all secretive about it infers to me that it's going to be different.
The Infinity page states that the online game is scheduled to come out in October. That message says late October/possibly November. Said it before and I'll say it again, it would make no sense at all to release a free online version and then the "regular" version that's out right now.
I don't have my hopes up. At all.
