No matter how much funding any project gets, development still takes the same amount of time - certain key people have to do certain key development and testing. It may help to speed up development to a certain level, but after a certain point there's no more noticeable benefit to throwing more money into it. Limitations are good. So, it will still take x amount of time and the window of opportunity has to be hit while it is still open. Another thing that funds can be used for is to ensure steady funding of promotional work as well as to help fund other projects built upon EOS.
