Bhai I know salman who wrote the blog and also referenced my blog on the same subject. As per available information it is GM6. Anyways I have asked my source to get me more info.
The recent article also mentioned that the 7th generation will be offered with 1.3L engine in Pakistan although the GN1/ 7th generation has not that option available overseas.
Third : Honda Atlas follow Honda Indonesia for product development and the 7th generation is not yet even available in Indonesia at this time.
I still have my doubts about 7th keeping in mind that GM6 is still in production even in India along side the new generation.
Again things can always change. The GM6 use the same platform as the current City we have and it will be much faster to develop while for the 7th generation, a plant need much more refinement and upgradation.
