The patch isn't finished. Our intent is to bring Survival DPS down to the level of some of the other dps specs while making Marks and BM more attractive in PvE. With pure DPS classes it is probably impossible to engineer a three-way tie on all encounters. However, we think we can make them close enough so that players can choose to play their favorite without feeling like they are a burden on the rest of the group.
For an overall approach, we made a few changes that will buff Survival, or even hunters in general. First, focus generation was lower as a result of a bug with haste buffs such as Hunting Party. We've fixed that bug, so focus generation will be higher now when that buff is present (presumably all the time for Survival). Second, we made Steady Shot scale with haste, which will let hunters get more attacks in overall and have more focus with which to do so. These changes would have been a net buff for Survival without additional nerfs to compensate.
We also changed Cobra Shot and the warrior ability Slam to scale with haste. This does not mean all physical cast-time abilities will automatically scale with haste though.
We did buff Frost Bolt. And we did buff Ice Lance when Fingers of Frost is up. However, we've decreased all Frost damage to Frozen targets by about 15% from previous values. The net result is intended to be that Frost Bolt is a little better against non-Frozen targets, and about the same versus Frozen targets. Ice Lance with FoF is still good, but Ice lance damage against Frozen targets is down a bit.
The intent isn't to nerf PvE frost at all, but instead reward Frost Bolt use in PvP a bit more, and reduce the damage and effectiveness of Ice Lance in PvP.
The important take away here is that datamined changes from pre-release builds and tests are not accurate ways for you to get information on intended game adjustments. Take it with a grain of salt, and approach it with a giant cup of curiosity.
