The launch of the most anticipated smartphone in the U.S. market - Apple's iPhone 5 - is expected to be just weeks away.

According to a TechCrunch report on comments from France Telecom Chief Executive Officer Stephane Richard, the iPhone 5 will come out on Oct. 15. This goes against the rumored release date of Oct. 7, which has been most recently reported by 9to5Mac.

While Apple is delaying the launch of its much-awaited smartphone, rival manufacturers like Motorola, Samsung and HTC have brought out high-end Android smartphones with the latest features. However, one thing that Apple's delay indicates to is that the Cupertino-based tech giant might have been silently working on what seems to be a product to answer them all.

The most rumored and highly expected features of iPhone 5 include Qualcomm Chip Support, iOS 5, iCloud, 8 megapixel dual-LED flash camera, 4-inch retina display, 4G networks for AT&T, Verizon and Sprint, 16/32/64 GB internal storage, NFC payment, 1.2-to-1.5 GHz dual-core A5 processor chip, 1GB of RAM and SIM-less design with two to three internal antennas for CDMA and GSM compatibility.

Meanwhile, with so many high-ended Android out (and ready to be out) in the market, smartphone users are spoiled for choices. Although iPhone continues to be the gold standard for the smartphone industry, its upcoming version tends to face a tough challenge from a string of 'smart' smartphones.

Here are the top five upcoming smartphone that can potentially halt Apple iPhone 5's run:

Samsung Galaxy Note

Announced at the IFA technology show in Berlin, this new device from Samsung features its Super AMOLED screen technology that offers a sharp 1280x800 WXGA resolution.
