You know, it IS possible that this might be an EA distributor/pricing issue: PC version went digital and a physical copy is doubtful but you might get it for X1 and PS. EA's retailer in India Game4u is showing the price as 4399 and is allowing you to preorder as a digital download. It was the same for FIFA 15 too. The PC version was a digital download whereas the others were physical copies.
Here see this: HomeShop: DAI for X1
and PSN
ie. Console versions are still on sale(for now). Doesn't make sense. I mean, there's a lot of other content with homosexual/violence themes and whatnot. Besides, would our government really even bother banning a game(here, people consider it a kiddie hobby). Again, origin India is based in India, unlike PSN(which is a reskinned EU site) the ban could be affecting that? Uggh, confusing.
Also this article suggests we might be seeing more games banned(as the total porn ban in India-God, why don't they just impose Sharia on the country??): Some slight NSFW content
Possible Solution:
My friend called EA Customer Care and they confirmed that keys from Amazon physical copies and third party sellers like GMG,G2A etc will work without any issue, and also that we can redeem the keys without the use of VPN. They do not have any information regarding the support of multi player and future patches. The Dragon Age Keep data can be imported without issues. (I dunno, he seemed hesitant. What happens if the game doesnt activate??)
So, we could use VPN, buy from online stores, ask a friend abroad to buy it for us, or maybe get it from third party sites(note: can download digital copy from Amazon.com, then activate it on origin, but provide a US address for billing and shipping)
My advice: Wait. Let the game launch, see what other users experience. Will any online content be available(Keep,MP,DLC,patches etc??) Devs have confirmed that the game works offline, so that's a relief.
