Despite of the fact that it is less than two months left till the launch of the highly-anticipated PlayStation 3 game console, the gaming machine still does not seem to be mature enough an technical problems still exist, according to an analyst, who claims that the part operates with constant errors and had to be rebooted.

PlayStation 3 units on display at the Tokyo Game Show about 10 days ago operated erratically and had to be repeatedly reset, according to a report released Monday by Macquarie Equities analyst David Gibson in Tokyo, reports Toronto Star news-paper.

“While the reason for this is unknown, we suspect it may be due to overheating as a result of enclosing the units and the high temperatures at the venue. We are concerned that such a problem has occurred so close to full production and is clearly negative news for the company,” Mr. Gibson is reported to have written.

This is no news that game consoles may operate incorrectly due to various reasons. For example, late last year numerous users claimed that their Xbox 360 game console worked instably or even produced graphics artifacts. Microsoft said at that time that even there were quite a number of people unsatisfied with the quality, their relative number as a part of those, who acquired Xbox 360 was not high.

The main concern for Sony now is that the demo consoles crash just weeks before product launch, which may potentially delay the release or cause necessity to replace the faulty consoles eventually. Additionally, crashes further rise question whether picking up the leading-edge technology, such as Cell or Blu-ray, was the right decision for the PlayStation 3.

Sony PlayStation 3 console is based on the Cell processor developed by IBM, Sony and Toshiba, the RSX graphics chip by Nvidia Corp. and will be equipped with Blu-ray optical disk drive, a hardware part, which is merely available today.
