I'd like to add some personal observations;
1. In the non-flashaholic world, Mag is not in danger of being "left behind", heck most people see them as THE flashlight company and buy cheap ol' plastic incans unless they want to upgrade the the "superior" Mag.
2. Magleds don't seem to sell around here. Why? It's not the last gen technology that turns Joe Average off, it's their price. Putting in the latest and greatest might not help that much in sales to Mr. Average, especially if they decide to up the price or even leave it the same.
3. Gummy dome Seoul + Mag + Joe Average = one f'd up dome. I've seem far to many bulbs break when a headless Mag takes a fall when tailstanding. Not to mention they seem to be a magnet for dust and junk.
I think tossing in the 060 Rebel is a good step forward, it may not be brighter, but as others said it'll have a tighter beam, possibly better tint and then there's the lower VF. What effect will the lower VF have anyway? Brighter or longer running? Not to mention that it gives them the chance to experiment with the Rebel, seeing if they like it and if they do, maybe they'll decide to upgrade to the TFFC.
