Current speed tiers in Northeast?

I’m currently on a TV and Internet contract that includes Performance Pro Internet and am paying an extra $20 for Blast. That gives me 300 Mbps down, 10 up. The contract expires next month.

Looking at Comcast’s promo site, I see what looks like the same exact plan I’m on except that it includes 300 Mbps down, which would actually be $20 per month cheaper than what I’m paying for.  Upload speeds aren't listed.  Is 300 Mbps currently Blast?

I care more about upload speeds than download speeds and want to know the upload speeds for all the current speed tiers.

Is there a list of the current download and upload speeds for the various speed tiers?
