We've wondering all day what Google will be announcing tomorrow, and we now have enough hints to make a fairly confident prediction: they will be announcing enhancements to the Android Market.
First, one of our readers tipped us off to the fact that a couple changes are showing up in the Market tonight. In the screenshot on this post, notice the History and Search icons in the suggestions. Those icons were not there earlier today, and as far as we can remember, the suggestions only previously included terms from your Market search history, not general search suggestions.
Additionally, the timing is about right for the "new payment options" hinted at last month to be announced. We're fairly sure those options will include carrier billing for more than T-Mobile U.S. customers, who are the only ones who can currently put app purchases on their phone bill.
Delving into the truly speculative, we hope that the Market enhancements announced tomorrow will include a web-based interface and/or media purchases via the Market, both features previewed at Google I/O.
