Utility of current accounting structure

Accounts are prepared for use of stakeholders. Mainly shareholders who need prospective as well as historic information to make decisions. But current accounting structure provides authentic historic information atleast a month after last date of FS in case of majority listed companies and later in case of unlisted companies. My question is why accountants are not preparing statements for future projections which can be used by shareholders. Why cant we move to real time information system where authentic financial information is available on demand as and when required!
