Worst case scenario, unleashed means MagSafe is back, m1 with two more cores unlocked at low end and the real upgraded chip on only the $3k and up high end.
Best case scenario, every Mac they introduce with the Pro label definitely gets a much faster chip than last years and the prices don't go up.
What we will probably end up with is how they did the iMacs, the low end one to keep the starting price the same as before (but it doesn't perform as well because its been crippled by something). The real upgrades start at a new higher price point than before but look, it comes with a colorful keyboard, maybe you won't notice. The high end will always be great, just at a price point non business users should think twice about spending for non critical, not for profit work.
We do not yet know what a Mac Pro will have in it. These chips are the middle of the road speed as far as apple silicon goes. And if they are breaking out warp effects for these, hopefully that means they are faster than we anticipated.
