I have no need for more resolution. At least, no real need. I've been shooting 16MP cams for the past 4 years (1Ds Mark II -> GH2 -> OM-D/X-E1), and have honestly never really felt any need for more. I'm not saying I'll never buy a higher resolution body (I have a feeling we won't have much of a choice eventually), but that I don't need it. I rarely print larger than 20" wide, with 16x20 and 12x18 being my most common print sizes, with the very occasional 20x30 thrown in. 16 MP is more than enough for a quality 20" print and looks pretty darn good at 30" as well. I've done one 40" print, and that starts to push it a bit, but it's really not a big deal. I do have one 60" canvas, but I took it with an E-P1 from an 18 image stitch, so there's more than enough resolution there (102MP).
I'd frankly rather save disk space and file processing time, as I just really don't run into resolution issues.
