The tradeoff that favors eink (marginally) is weight + battery since LCD can match most everything else. So the balance of power between the camps isn't going to change; eink isn't getting viable color or any new must have feature. And we're already at the point where "entry level" = backlit touchscreen. People who like LCD have ample choice of tablets and large phones and those who prefer eink have their choices. No compelling needs drive the market.

The technology doesn't look to get significantly better any time soon and neither do user needs. It's like tricycles: it's a small market that does what it needs to do at a fair enough price and doesn't show enough growth potential for anybody to throw R&D money at it.
