I don't know what you mean about enhancements in the buffer
pool. For an in-memory database, there shouldn't be a buffer
pool in the first place, as it is *all* in memory.
You are right: In-memory DBs are making buffer-pooling obsolete -
except for making data persistent (see below).
I would be very reluctant to use any database engine which considered
disk access obsolete.
The disk is not obsolete but something called 'anti-caching' is used:

Are there any show cases out there?
What did the HANA users have to say? Seems like they would be in the
best position to provide the test cases.
This paper provides some insights into the research behind HANA
