are these specs real? 1536 SPs, 48ROPs and so on!?

or did he get the specs from a 470M or something?
No they are not real. It's placeholder, same as the RX 460.
I don't know why you guys give credence to such nonsense.
There's only been 2 SP counts that are reliable for C4 and C7, that's 2048 SP and 2304 SP. Since RX 480 is already confirmed to be 36 CU or 2304 SP, it stands to reason the same leak will be true for RX 470 at 2048 SP.
As for people being so negative about AMD's slides. Drivers 16.1 and 16.2 are from January and Feb. Do you think AMD have optimized for Polaris back then already? Remember what they said in CES (Jan), demo was running on ES sample with non-optimized drivers.
The interesting thing here is why AMD deliberately send out such misleading info that's using very out-dated drivers, and they included a very specific disclaimer "results may vary due to use of drivers"... why do that?
We have other leaks, claimed review samples that have different bioses, and recently, claimed retail samples, which show much better results using more current drivers.
This looks like a misinformation campaign all the way to the launch reviews.
