Premium seats = 25% price increase?

Just got an email to be "added to the waitlist" for premium seats.
Blog post here:

Cost is $125/Month.

What this gets you:

5x more usage than standard.

No 5 hour time limit.

Weekly reset.

That sounds suspiciously like the current $100 plan. Is this just a price increase disguised as an upgrade, with a downgrade for those who don't take it? Or am I missing something?
