M8 is fine, sure, but that was just about done. What about the roadmap after M8? My contacts inside of hardware tell me that the entire CAD group is gone, pretty much, as is much of design. Sustaining is in relatively good shape, but there were layoffs even there.
If there is a future for Sparc all Oracle has to do is to be open about it and the layoffs. But, it being Oracle, not likely.
Oracle doesn't tell its employees any more than it tells the outside world. Someone I know who is in the former PeopleSoft group had no clue about this until I told her.
Back when I was a customer I bought some of the first Sparc workstations. Too bad they couldn't sell it any more.
