They seem to be going further than I expected which is good. But this will be a nightmare to balance and they still haven't said anything about the balance they want to have.
In either case, as I can see it these are the pressures which will affect the market after this goes live:
1. T1m0 loot reduction => less minerals => upwards price pressure
2. Mineral distribution changes => downwards pressure in general on the minerals they are boosting in 0.0 (mostly trit and pye I expect)
3. Insurance on T2 raised => demand up on T2 as they are made more affordable => upwards pressure on moon-goo (this effect is probably not going to be very large as the demand on T2 isn't very dynamic and the basis of warfare will still be battleships)
4. Insurance made dynamic => downward spiral on minerals (this effect is uncertain, it depends on IF the m0 loot reduction are larger than the usage of minerals by "insurance fraud")
5. Supercap insurance changes => supercaps being used less => reduction in supercap losses => reduction in demand for minerals => downwards pressure
Then there is one they haven't mentioned.
6. Capital insurance??? Are these changed to the same as supercaps? if so it will be a massive change on demand for minerals as sov warfare becomes prohibitively expensive for all but the largest of entities. Which in turn will solidify the mega alliances hold over 0.0 and that is a pet-peeve of mine

Overall effect is difficult to see as CCP are tweaking a lot of nobs at once.
Ideally the two major forces will be meta0 reduction and insurance made dynamic.
To know if the price will stabilize around some decent number or just have a downward spiral depends on if the "insurance fraud" mineral sink is smaller or larger than the m0 mineral faucet. If assume that 50% of all minerals are used in "insurance fraud" and 10% of the total minerals come from the m0 loot they are reducing then prices will plummet. If it is the other way around, prices will go up, unless stabilized by the insurance change to supercaps.
Ideally the m0 reduction and "insurance fraud" have about equal weight, preferably slightly larger for the reduction to offset the other changes. Which would leave the mineral price around where it is right now. This would of course make warfare more expensive, losing a BS will cost around 30-40m more than today.
