There is no 3.14.707.x for ASIA_WWE;
The 3.14+ version was distributed mainly for bugfixes for some region.
Despite bugfixing, many of us *feels* there are some improvements as well.
HTC never distributing 3.14+ to many other regions because there is no need or the improvements is minor. When time come you will likely to receive 3.14-4.20 OTA, full stop.
