for me i noticed a big increase of interest concerning pc engine games in europe, since every wii user (with net access) can easily DL the good ol' games for cheap they may be never could play back in the days when they where popular. as many of you know, the pc engine was never released in europa officially, therefore only a small amount of people could get into the facinating world of NEC gaming. this may change now and many of the meanwhile elder people can finally join this world legally and without paying a small fortune. in our german language forums as well as here, the request for good pce soft-recommendations is higher than ever before.
if this all will have an impact to the prices for original soft, i really don't know. but since most of the people collecting those stuff rather than just playing it, i think there won't be a big drop.
