Best possible outcome: red is only one item, difficult to get with a small bonus and the final change for a long time. Only available for about 5 heroes, out of which 3 are already typically used.
Worst possible outcome: red is 1+6 items, mostly for unused heroes, needing 4 or 5 times more items. Still every single if these can easily blow away every possible c4 team, starting a whole new meta. Also red+1 will follow around september.
...The second is about what I expect.
