As for the reasons why they don't build anything big since IL-96-300, I would say one of the primary reasons is dissolution of USSR and subsequent shrink in aviation industrial sector. It's been 25 years since then, but they had total chaos in aviation industry in the 90-s.
Is the Il-96-400 just a rumor? As far as I know it's well under way with first flight expected in 2019. Two Russian airlines, including Rossiya said to be interested. It's supposed to limit Russian dependency on foreign aircraft manufacturers (something important considering the actual tension between Russia and the US and EU). There is plenty of article around.
