Rumor is Cell Carriers are not happy with this... So Cell Carrier updates are in the works to block out certain access to some types of "services" to maximize data usage..
Just like the internet can block certain ports for Peer to Peer or VOIP, they want to block games, emails and web browsing on Wifi so you must use data at a cost..
Which would really such, because I heavily depend on it when I travel States side and my counterparts the same when they come up here.. I hate having data plan roaming charges of $500.00 for a week not including phone calls..
But you can see where greed is a driving factor with less competition.
The excuse will be, WiFi drains batteries too much , which it does in a way but I rather it drain my battery than my wallet..
