I know that it is bought to sell the PPC hardware but from a economic view would it not make more sense to stay 68k and update/bugfix/improve what is there? For classic users it would be more interesting and it would still run on PPC hardware, at least in emulation, in best case even on petunia. If you want PPC native versions you have to invest lots of time (and thus money) to get it reworked and to replace asm parts, lots of work and no real new features and thus no reason to buy it.
