I agree with the OP, I hope they continue to put out new editions every 5-7 years for awhile.
I have played every edition of D&D from Holmes Basic on. At some point in the life of every edition, I have stopped playing it out of dissatisfaction. Took longer with some editions, I played 1e AD&D for a good 10 years before I set it aside shortly before 2e ame out. Some trials were briefer, I canceled a 3e campaign after about 6 months and have never used that version since.
The point is, each new version addressed some of the reasons I put aside prior versions, more or less successfully, and each version added some things that became problems for me over time. The core concepts of D&D are very engaging and I want the game to better. Even in it's 6th major pass, the game does not yet feel like it's done.
When an edition is finally released that feels, to me, like they finally got it just right, I will no doubt feel like GregoryOatmeal and want that version to remain perennially in print (whatever "print" is at that point). For now though, I want the designers to keep working on it. The game still aint done.
