RS50 vs 50PL @ 40A. I honestly doubt it'll be able to beat the 50PL in terms of maximum CDR before heating up past 80C, or cycle life, but it might yield a little bit higher runtime at some current levels in the 15 - 35A range... I doubt it'll be able to compete with the P60B when it comes out though, not to mention the JP50 and the 50D. Very competitive market here!

At this point, we never know. When I first saw the EVE 50PL and noticed an IR higher than 3 mOhms, the first thing that came to my mind was, "this cell is not going to be better than the JP40," because the JP40 has an IR of around 2.4 to 2.6 mOhms. But surprise IR is not everything.
We also noticed in the performance of the 50PL that the higher the current goes over 30A, the more Ah it can discharge, which is something normally very contradicting. Talking about this with John, I believe it is just the right temperature at the right moment the sweet spot—where temperature helps lower the IR and allows the electrolytes to flow better without negatively affecting performance. We are talking about just 20 to 30 mAh more, but we see this happening between 30A and 45A.
At the end of the day, anything is possible.

Do you know when the cells will arrive? I wanted to buy 50PL cells for my 32S battery, but unfortunately, the cells aren't mature enough for a 32S 134.4V battery. I recently received an offer for 50RS cells, which are supposedly better than 50PL cells and perfect for a 32S 134.4V battery. I don't want to invest so much money in a battery that I don't even know if it will work. Like with the last 50PL test video, I hope to see the 50RS cells in person to see if they match the datasheet. Thank you for your great videos.
Best regards

So sorry to bother you, but could you please share where are you buying cells, maybe the is reliable dealer?

Here are some news, to take with a pinch of salt:
The upcoming Molicel P60B might be a 5.5Ah cell after all, around 20Wh.
This would put BAK's 55B cell in the same ballpark, though 55B caps out around +2C charging.
Start of production for the P60B is tentatively slated for the end of the year, but again that's unconfirmed.
In the meantime, we will see whether XA3, Molicel's first full-tab cell will get a minor energy boost, or if ultra power has remained the core focus.
It is also exciting that Ampace is moving forward with its JP50. If sampling is any indication @thermal_runaway, mass production shouldn't be too long, now.
Between Molicel's P50B, EVE's 50PL, BAK's 50D, Reliance's RS50, and Ampace's JP50, as @h1tec said, it's certainly a very competitive market right now!
P.S: About:Energy seems to have populated their entry of the P60B (here). Has sampling started?

Regarding Reliance's 21700 full-tab cells that are in production, RS40 and RS50, the technical datasheets can be found here for RS40 and here for RS50. I am attaching both for simplicity.
The summary for 21700 and 46mm cells as presented on Reliance's website (source):

Small update
Update:
- more cycles in 5C charts
- added separated 20A discharge chart, the reason for this is the limitation of my BTS-4000 test system to 20A. I hope to add Moli P50B running at 20A soon.
- added EVE 50PL and Ampace JP30 with 5C and 10C Voltage discharge charts.
Comments:
- my discharge charts of EVE 50PL samples from Vapcell are comparable to @ZEUS-FL or @BatteryMooch results, I just use different (Time) scale on X-axis.
- cycle life of EVE 50PL samples from Vapcell looks good so far
