LONDON -- We have already taken a look at news expected next week from some of our most popular FTSE 100 companies, but it's set to be a fairly busy week, with quite a few bringing us updates. Here are three more we should be hearing from next week.

Rio Tinto (LSE:RIO) (NYSE:RIO)
On Tuesday we are due a first-quarter operations review from Rio Tinto. Anyone who has been watching the sector will know what an erratic time the miners have been having. Rio Tinto shares are down more than 15% since mid-February to 3,075 pence at the time of writing -- but that came after a climb from last September's lows of about 2,715 pence.

The firm's final operational update for 2012, released in January, told us of a strong finish to the year with "record annual iron ore production and shipments" of 247 million tonnes. Forecasts for 2013 suggest earnings per share of about 430 pence, putting the shares on a forward price-to-earnings ratio of only a little more than, which looks cheap to me -- but this year will be dependent on demand, which is uncertain.

SABMiller (LSE: SAB)
We have a fourth-quarter update coming from drinks giant SABMiller on Thursday, with full-year results to follow on May 23. In the firm's third-quarter update in January, the owner of the Peroni, Grolsch, and Miller brands, among many around the world, reported an 8% rise in organic group revenue.

SABMiller's share price has gained 30% since the start of the year to reach 4,439 pence today, easily outstripping the index. But that's only a small part of the story; if that carries on to the end of 2013, SABMiller's share price growth will have beaten the FTSE for 13 straight years!

William Hill (LSE:WMH)
Friday is time for a first-quarter update from William Hill and if 2013 turns out as good as 2012, shareholders will be in for a treat. The bookmaker reported a 21% rise in pre-tax profit for 2012 and boosted its dividend by 17% to 11.2 pence per share for a yield of 3% on today's 387 pence share price. And that share price is up more than 60% over the past 12 months.

However, forecasts for this year are currently pretty flat, with no rise in EPS expected at the moment, and there's no real change in the dividend predicted, either. The shares are on a forward P/E of 14, which is pretty average for the FTSE.

Finally, dividends can add nicely to your investment returns -- they can be spent or reinvested, according to your needs. Whether you're investing for income or growth, good old cash is always welcome. And that's why I recommend the brand-new Fool report "The Motley Fool's Top Income Share For 2013," in which our top analysts identify a share that they believe will provide handsome dividend income for years to come.
