The problem as I see it is that either way, they are going to irritate their customers (not that Pentax ever seems concerned about that).
If this is the start of a trend, and they continue it into a new high spec camera, they irritate present istD users who want to upgrade.
If it is not the start of a trend, and they put out a high spec camera that uses CF cards, they irritate the istDS user who is looking for an upgrade path.
IMO, using an SD card in the *ist Ds makes sense as an upgrade from a digital P&S to a DSLR. The vast majority of digital P&S (with the exception of Sony and Fuji), us SD cards
