Um, WiFi is not in any way related to 3G/4G/GSM.

WiFi is 802.11a/b/g/n. If the only way to connect to the internet in a particular place is over the cell data network, then the modem/dialer will be hooked up to the router so that all devices can share the connection, not WOZ. Heck, most phones can become their own hotspots now.

WiFi is everywhere. Hotels, coffee shops, restaurants, public buildings, book stores, arcades, convention centers, my bedroom right now as I type this. Jack only needs to add WiFi and ideally a wired ethernet connector in WOZ and his end of the job will be done. The rest is up to you.

Regarding fans, Jack has said so far the fan count is currently at "maximum" and they plan on figuring out which ones they can take out before shipping. I'm not a fan of fans either, but even if the boards were in the backbox, there WOULD have to be fans (Stern's low-end CPU board doesn't produce any significant amount of heat compare to a computer capable of 4+ streams of HD video plus overlays plus controlling the actual game).

correct on everything u said.

the prev posts got mudled up cause a few were changed after posting answers and it gets/got confusing.lol
yes, if they spend the money on the wi-fi hardware, then the wifi updates will be excellent.

I will add, I did forget that JJP is using a computer style arrangement versus what Stern has been successfully been using because WOZ has the graphics requirements for the LCD etc and needs alot more processing power, hence the fans are required etc etc.  Overall, it seems to be fully loaded thats for sure..hope gameplay is good enough to have all this stuff built around it.......
