M+ loot this week and next week question

I read the bluepost talking about the week of Jan 21, but it looks a little confusing for me.

Correct me if I’m wrong, but this is my understanding:

  • End-of-run rewards will be capped at 445, so if I complete a +15 will be the same as a +6.
  • Weekly chest that we will open in Jan 21 will contain a piece of gear scaling up to +10, can be titanforged but cannot be corrupted. The ilvl will be the same as what we already had before (a +10 will give a 440 with chance of titanforge).
  • Weekly chest that we will open in Jan 28 will contain a piece of gear scaling up to +15, cannot be titanforged but will always be corrupted. The ilvl will be increased from before (a +15 will give a 475 corrupted).

Am I missing something?
