Welcome to the end of bitcoin. Nobody can make a ROI mining and so existing miners will just consolidate until one has 51% and then everyone will stop using bitcoin.

It's pointless for anybody to buy new hardware now as the more is actually delivered the more it will become obsolete by rising difficulty.

No new miners means no new bitcoin owners with money to spend so shrinking bitcoin economy. It's been a fascinating experiment that looked as though it might actually work but alas the rising difficulty that protected it will actually kill it IMHO.
