Hi, I'm asking to the shop 
Even their name is gone 

I'm trying to reach them since the 13/03 but no luck... They don't answer to any of my messages and the store is still close

Looks like a new frame from these guys just dropped....

Never seen that frame and I always order via the HIMALO Store

You could ask them on the chat, they are quite responsive.
What's strange with your link is:
1) the video linked on the store page is not for the same frame
2) they only propose the frame in S

It's probably a new frame they released after the new year but it was not yet there when I ordered mine in January. Basically it's the same frame with a new location for the rear shock

Hi everyone, I wanted to inform you that the Version 3 of the Himalo Fast work 150 is available on the Himalo store (Ali)

Main change are:
* Shorter chainstay for the 29"
* Better tyre clearance, from 2.4 to 2.5 on 29"
* Better cable management
* Reinforced the bottom bracket and other welding
* The seatpost in now 31.6 in place of 30.9
* New screw for the pivot
* Will see when I receive it but the welding or the paint look smoother ?

Only downside I see actually is that it weight 200gr more (3730gr vs 3950gr).

I've ordered one to replace my old V1.
It will be in mint green, if I'm lucky it should be there in 3 weeks 

They have also planned another version with bigger travel and trunnion mount for the shock:

... My frame is already creaking but it could be my shock bushings not sure yet. I'm going to order new ones and then I'll be able to know for sure where the creaking is from...

The creaking noise is probably coming from the igus bushing, I've a shock from Suntour with the same bushing and I need to cleanup and grease again regularly.
Regarding the head offset, it's costly, but you could add an angle headset (from 1° up to 2°) from Works Components

Marcram, why putting horizontal Drops on a full ?
You will still need a chaine/belt tensioner, but you will have to check if your axe is compatible with the width of more than 148mm (Boost) and the holes of 12mm
