Why no PAL prog scan?

[cuewoz1]

It seems a lot of dvd players do progressive scan in NTSC but not PAL.
This is the only thing putting me offf the pioneer 565 player I have recently seen.
Does it look different if the disc gets transfered to NTSC first? I'm thinking it would do.
Is this enough to put you off a player

PAL prog has only recently been ratified, hence the delay but there are now quite a few players capable of both e.g. Sony 930/730 , Samsung 935, Yamaha? and HK models do.
If you spend more you also get both SACD and DVD-A.
