Manufactures don't do that often. They might have a couple different battery lines, but everytime there is a new standard buyers have opportunity to check out the competition. I standardized on Dewalt 20/60 volt tools, I don't even look at other brands anymore as then I need to invest in batteries when I already have plenty of batteries so Dewalt is almost always cheaper because I'm buying a tool without a battery,
Sometimes a 12volt tool looks good (lighter), but so far I don't have any. If I ever do I'll be comparing all the brands (and their catalog) to see which I think is best, already having Dewalt 20 volt tools gives them no advantage (My dewalt radio can take 12 or 20 volt batteries, but that isn't enough of an advantage)
