Explanation in my opinion:
historical business reasons.
In germany there was a heavy fight in seeling more units between Genius
and Fritz.
Fritz-company always claimed that fritz is a good blitz-program due to
advertising campaigns where Fritz had to play against Kasparov and other
players in blitz or active chess. Therefore the traditional good blitz
program Genius had to be TUNED to stand Fritz or get as good results in
tactical test-suites like Fritz.
In the end all this TUNING of Genius made Genius weaker imo.
Genius lost the race with Fritz.

I guess Richard is a very nice person. He cannot write a
massive-attacking-monster killer program like others can create.
He is more a nice guy.
Genius always played like Richard behaved, in the end, it looks Richard
lost the race because he was unable to defend against people attacking
genius.
He was not able to DEFEND or stand the attacks.
Ossi always tried to force him to stand them, and helped, but you cannot
make a samurei out of a pacifist.
Fritz on the other hand, armed with big hash, power-books and a very
tough team (the genius team was IMO too much directed by Ossi. Team work
is not ONE master and a few workers, team work is MORE. In the end this
team was not good enough)

The race is over. There is no more genius.
They said they would tranfer it from 16 bit assembler into 32 bit
assembler.
But I don't believe it takes so much time. I have the feeling the
relationship between ossi and richard is broken and for this reason
there is no more Genius follower. But this is only my explanation.

I still think tuning genius into a wild animal/beast was wrong.
They would have done better to increase genius strengths instead of
trying to exchange genius-weaknesses by implementing extensions for
tactict and changing its style. It played boring. This was
system-imanent. YOu cannot change this the way they tried to open the
playing style in Genius4. Genius5 took back those efforts.

Will there ever be another genius.
I hope so. But the chances are low, or ?
Lets keep the fingers crossed.
