1) I will be converting fully to 4e.
2) I will continue to purchase adventure paths and Game Mastery modules.
3) I will purchase edition neutral products that I feel would be useful in my games.
I will be purchasing the 3 core books guaranteed but it will be a while before I actually use these. I am currently playing in a Ptolus game and MC's World of Darkness game and both of those will probably last through 2008. I am currently running Expedition to Castle Ravenloft and that will wrap up around the 4e release but I already plan on running Rise of the Runelords for that group next. With the groups I play with we will probably dip back into 3.5 once we make the 4e switch.
