Future of DSD in Blu Ray era

Fair use excerpts from www.blu-ray.com

What audio codecs will Blu-ray support?

Linear PCM (LPCM) - offers up to 8 channels of uncompressed audio.
Dolby Digital (DD) - format used for DVDs also known as AC3, offers 5.1-channel surround sound.
Dolby Digital Plus (DD+) - extension of DD, offers increased bitrates and 7.1-channel surround sound.
Dolby TrueHD - extension of MLP Lossless, offers lossless encoding of up to 8 channels of audio.
DTS Digital Surround - format used for DVDs, offers 5.1-channel surround sound.
DTS-HD - extension of DTS, offers increased bitrates and up to 8 channels of audio.

No DSD!!

Does it mean DSD is esentially side lined or even worse, dead?

I believe that Sony's DSD will continue to be used for audio-only recordings, especially multichannel ones, and that SACDs will become a niche (hi-rez-digital) product, just as LPs are a hi-res-analogue source but still somewhat of a niche product.
