Are you being sarcastic? It's the same drive, just slightly different firmware. There could also be some difference regarding the quality of inner components.. but all-in-all it's pretty much the same. Coming to this forecast by looking at the specs and the "differences" between previous Black and RE 7.2k rpm drives. Also it's much cheaper to use the same design as often as you can.
It needs to be cooler and quieter than the RE4. But, with all the technologies they've added, it'll no doubt be a totally new drive internally.
At 5 platters @ 7.2k rpm it's not going to be quite. And at 8 W idle power consumption it's not going to be cool. But both specs are not the purpose of this drive anyway.

I think i will wait for the 4TB green with the 1TB per platter, I am more interested in cheap space then expensive space with marginally better access times. At this point if i wanted access times and speed i would jut invest in a larger SSD
If it's like the 2TB Black, it'll have average random access times of around 12ms, maybe 11.8 if I remember correctly, thanks to the peizo wrist. That is competitive. But yeah if it's crazy expensive then not worth it but if you're like me, you'll wait 2 years and then buy it for $90 or something.

But only if it's alread got 730 days of uptime on the clock, right? New HDD prices haven't moved much during the entire year, don't expect this to change anytime soon.

In which case, only the 4TB and 2TB drives have the piezoelectric servo wrist for a bit quicker random r/w performance
Somehow they managed to theoretically reduce power consumption from the 2TB 4-platter model of 10.7W/8.2W to the 4TB 5-platter model at 10.4W/8.1W ((read/write)/idle)
There has got to be some issue with making mass volumes of 1TB (500GB/side) platters, or the heads.
