Demo data to full game

Never heard of data being transferred from a demo to the full game... there's a possibility it may do so for the MP component, but that'd be all I expect.

Looks like she will, just had a look on the demo page and it says. Note: Karma, skills, and other data acquired in the demo version can be transferred to the full version.

There are demos for NG2 and Razor's Edge, get some practice in on those. The NG2 demo is a slightly cut version of the first chapter. You get a few weapons to play with but they are maxed out so their move set is different than you begin with in the full
game.

The RE demo on the other hand starts you with 2 weapons for Ryu that you level up by playing and upgrading yourself, anything you upgrade in the demo carries over to the full game if you choose to import the demo save data. You play as both Ryu and Ayane
in the demo so anything unlocked with either character will carry over.

As for Yaiba I'll play it but it's absolutely going to be a bargain bin buy, so about 2 weeks after release then!

The catch is that the demos are just that: demos. Not the full games.

XBLM also had some problems with people getting the Fable II download game full instead of the demo version a while back for free. That could probably be the reason.

But transferring your license and recovering your gamer tag should suffice if it is indeed the full game, but it should be nearly 7GB of data, not 1.5-2GB.
