Before the market opens tomorrow morning, Carnival Corporation (NYSE: CCL) will be reporting its fiscal third quarter earnings results.

The last time the company reported earnings was back on June 18 when it was able to post 33 cents per share, above the 29 cents that analysts had been expecting. This time analysts are looking to see the company show earnings of $1.18.

So far this has been a pretty decent earnings season, and soft drink giant PepsiCo, Inc. (NYSE: PEP) gets its turn to impress Wall Street tomorrow morning when it releases its second quarter numbers.

The company will be announcing its second quarter earnings before the market opens tomorrow, and analysts are expecting to see earnings of $1.00 a share from the world's second largest beverage maker. For the same period last year PepsiCo posted earnings of $1.03.

Shares of Tiffany and Co. (NYSE: TIF) fell nearly 3% today as traders prepared for tomorrow's third quarter earnings release. The company is scheduled to report its recent quarterly numbers tomorrow morning before the opening bell.

When the company announces its earnings, analysts are expecting to see earnings of 25 cents per share. The last time that the company reported was back on August 30 when it reported 45 cents a share for its second quarter, easily beating analyst estimates of 34 cents.

One analyst, David Schick from Stifel Nicolaus & Co., told investors in a research note that he expected a good quarter from Tiffany's. He cited the currently weak dollar as the main reason, stating that the weak dollar should result in strong U.S. sales of new products, and foreign tourism. Schick currently has a "buy" rating on the stock.

Dell Inc. (NASD: DELL) had a better quarter than expected. But, the highlight of its earnings release was the announcement that it would let go 8,800 people, about 10% of its staff. After job cuts by Motorola, Inc. (NYSE: MOT) and International Business Machines Corp. (NYSE: IBM), it is beginning to look like a mature tech trend.

Dell benefited from raising prices on its PCs and getting components for less money. Reading between the lines, that may be bad for Intel Corp. (NASD:INTC) and Advanced Micro Devices, Inc. (NYSE: AMD) both of which supply Dell with x86 chips for servers and PCs.

For its first fiscal quarter of 2008, Dell had revenue of $14.6 billion, operating income of $947 million and earnings per share of $0.34. Revenue was up 3% and net was off a fraction. Results are still preliminary because the company is in the midst of an accounting probe involving the Justice Department.

Dell has a 14% year-on-year improvement in average selling prices. So, the company's focus on selling machines with more features at a better price worked fairly well.

Dell maintained its lead in the US server market and server revenue led the company's revenue improvement with growth of 19 percent year on year to $1.6 billion. Revenue from laptops rose slightly to $4 billion and desktop revenue dropped slightly to $4.9 billion.

Dell's near-term future seems to be based on two things. The first is whether it can cut 10% of its people without hurting service. If so, the savings are considerable going forward. The other project that needs to work for Dell is putting its computers into retail outlets like Wal-Mart Stores, Inc. (NYSE:WMT). With only 3% revenue growth, it needs another sales channel to restart top-line growth.
