Two Questions about Versions

Hi,
I found two accounts on Github about NEM:
https://github.com/NemProject
https://github.com/Nemtech

My First Question is: Why won’t you merge these accounts into ONE account?
Seems one of them is for NEM-V1 and other one is for Nem-V2.

My Second Question is: Until when Nem1(java based) will be continued to develop after catapult(C++ based) release? Is there any “discontinue date” for NemV1 ?

Thanks
