Everyone would like to see a demo. I would like to see a demo, but do you really want to start a poll for a demo? I've seen polls with over five thousand votes before on whether or not to keep a playlist. One such playlist was on RBTB. I even voted to keep it, but did it do anything? No, it did not.
Be patient. Either there will be a demo out soon or there will not be a demo out soon because it will only be a few months before Halo: ODST (RECON) hits the shelves. If it happens, great! If not, you only have to wait a few months! Be optimistic!
Either way, you win.
