Questions regarding the future transition to "Marks of Victory"

In case anyone may have missed it, there is some pretty big news that was just announced here: What's Next For DCUO: New Plans For Future Episodes.

While there is a ton of information contained within that thread and its OP (not to mention at least twenty pages of various bloat and responses as of this writing), one thing stood out in particular: that we will be transitioning from Marks of Triumph (MoT) and Marks of Fury (MoF) to one universal currency of Marks of Victory (MoV).

Now, while Mepps would later go on to make a FAQ later on in that very thread, I feel like there are still a bunch of unanswered questions* and unknowns as far as this transition is concerned.

*These series of questions will be asked in the following post, since there probably won't be enough room to contain everything here.

In no particular order:

1. How does this change affect the Vault? The Vault was only fairly recently updated so that MoT or MoF rewards from the Vault would scale with a player's CR. With this new change, will the Vault be considered "solo content" and reward 1 MoV? Will there be no MoV reward from the Vault at all?

2. How does this change affect the Promethium Lockboxes? Promethium Lockbox rewards of MoT or MoF used to scale in regard to a player's CR. In a similar question with the Vault, will Promethium Lockboxes reward 1 MoV when opened, or will they now only reward the usual random Aura, Base Item, Soder, or Style?

3. How will rewards be changed as far as Bounties are concerned? If players are of current tier for the Bounty that they are running, how are the rewards for MoV determined? Are Bounties being considered a type of open-world Raid-content like an Operation (since a Bounty run would theoretically require eight people if everyone involved is at tier) and reward 10 MoV? Are Bounties considered something entirely different, and reward a different amount of MoV instead of what Spytle listed for Solo/Duo/Alert/Raid content in the other thread?

4. Will T4 ever be revisited and/or expanded? Okay, now lets address the elephant in the room. Unless you are a Raid enthusiast (Bounties included, since I mentioned above that players would more than likely need a raid-group to complete them at tier), T4 seems to be severely lacking in content, with only two daily solo, non-instanced missions (and two instanced missions offered only once every five days) from the "Home Turf" DLC/Episode, one four-player Operation from the "Hand of Fate" DLC/Episode, and one F2P Alert (also probably considered the worst Alert in the game), it appears that there are less ways to accumulate MoV than any tier before this. This is further exasperated with the fact that T4 has no queuable Solo content, and absolutely no Duo content whatsoever. Is there any hope for T4 to be revisited and/or expanded to include Solo/Duo content (even if it is rehashed; Metro Station and Temple of Crime come to mind as they are prior levelling instances available to both heroes and villains) as a way to earn MoV for "small-content" players to help get to T5?
