There's never a dull week on Wall Street. Let's go over some of the news that will shape the week to come.

The new trading week kicks off with BIOLASE (NASDAQ:BIOL) reporting. The biomedical company that makes lasers for dentistry and medicine saw shares crash this summer, after warning that it no longer expects to generate cash from operations this year. At the time it did expect to turn positive by the fourth quarter, but we'll see what kind of insight BIOLASE provides on Monday afternoon.

RealD (UNKNOWN:RLD.DL) reports on Tuesday. The leading multiplex 3-D outfitter has seen its rate of installations slow lately, leading RealD to announce that it will lay off 20% of its staff. Did they see this coming? If so, it's not thanks to the company's 3-D glasses and projection systems. 

Tuesday probably won't be pretty. Analysts see RealD's quarterly deficit more than doubling from a year earlier on a 22% slide in revenue. 

ExOne (NASDAQ:XONE) isn't as popular with investors as the larger stars of the 3-D printing realm, but it doesn't mean it hasn't been successful. Stock of the provider of 3-D printers and related products to industrial customers has more than tripled since going public at $18 earlier this year. The company announced Thursday that it will open its seventh production service center next month.

ExOne reports on Wednesday. It hasn't been consistently profitable the way the industry's two largest players have been, but analysts do see ExOne posting its first quarterly profit as a public company on Wednesday. 

China's been a volatile playground for investors, and one of the biggest swingers has been E-Commerce China Dangdang (NYSE:DANG). The leading online retailer of books reports on Thursday. Wall Street sees a narrowing deficit on a 28% surge in sales.

The market is typically quiet on Friday, but that won't stop Sony (NYSE:SNE) from making waves. The Japanese consumer-electronics giant releases PlayStation 4, hoping to woo die-hard gamers. The console is priced at $399. That's not cheap, but it is $100 less than what the Xbox One will hit the market at a week later.
