fewer miner means that those fewer miner get more coin... because total no. of minted coin stay the same.
Not if the few ones left keep buying more hash generator things. If this happens, we will see mining concentrated in the hands of few and will be harder and harder for newcomer have profits(any similarities with current situation is just coincidence)
See above ... if that smaller group then buy more rigs in the same proportions, the number of minted coins they receive will not change at all (with the exception of what I wrote in my previous post) so I don't really get your point.
As for newcomers they have the advantage of being able to buy the newest, fastest rigs on the market, so as long as they have done their maths right and can run a business, there is still no barrier to entry. In fact they may be more competitive than the incumbents if they ONLY have the newest and fastest gear and a good set up. The landscape can change quite dramatically. Though, I agree, it is and will likely remain open to those with deep pockets.
It is those with obsolete equipment that are the losers, as it always has been in any industry. Nothing else really changes.
