If they feel that Chessnut - and Millennium for that matter - are hurting their sales in the home user market, they might. If they still are experiening growth with their current product range... it would have to be a strategic decision to allocate development resources for that. For the use cases "analysis at home" and "offline play at home", they probably have very high market shares. For use case "play online at home", I am not sure... maybe Millennium has a higher share. If that is a very fast growing segment with high potential, this strategic decision would be wise to take. Because a competitors success in this segment might leak into the others.
As far as I know DGT had some problems with manufacturing (scrap), when producing the DGT Revelation II (AE) which is essentially a wooden DGT board with LED and an integrated computer. Also the price point was geared more towards collectors, not online players.
The DGT Revelation II AE can be used as a tournament sized online board, to answer your initial question :-) Not sure, if the current LiveChess drivers support the LED anymore.
Will DGT ever come up with a similar e chessboard as good as Chessnut Pro ?
