Pin-Pointing the Wii's accuracy

At E3 a few gamers said that "WiiMote" could use some tweaking because of some glitches, mis-communications, and inaccuracy. A few months later, has anything changed?

During Nintendo's press conference on September 14th some press and gamers were given the chance to play some of the Wii titles. Some of these titles were shown at E3 and new builds of the titles were available to see progress of change.

A few press folks have called the WiiMotes accuracy into question. Gamespy's preview of Trauma Center: Second Opinion said "cutting and stitching is difficult with the remote." Kotaku's Brian Crecente said that Red Steel controls were "Janky" and have not progressed as far as he would have hoped since the E3 presentation:

"It just feels like the controls are a little loose for a shooter. I didn't feel like the reticule was aiming where I was pointing exactly, or when I was pointing there."

What can be worse then inaccuracy? Loosing the controller signal:

"Even worse, the game would just lose my controller at times. Apparently what would happen was that my pointer would slip out of the sensor's borders for a second, making the screen kind of slip around while I tried to get it to start recongizing my remote again."

Brian said that the remote lost signal "a few times" during his five minutes of gaming. Other reviews from Gamespy praised the remote as working "better than expected" in games like Marvel: Ultimate Alliance which is not, however, a first-person-shooter.

Is this an FPS issue that can be refined with more tweaking? Perhaps developers just need more time to get comfortable with the hardware? Or, is the hardware just not going to be capable of pin-point accuracy which is needed for the FPS genre?
