It figures out in 2015 there will be about 105 million high-definition Blu-ray Disc sold, although it is still under the 141 million DVD players shipped in 2006 at its peak.

"Blu-ray recorders will replace DVD recorders," said Norm Bogen, VP digital entertainment with In-Stat.

"Many consumers of recorders will even drop the physical disk media option altogether and instead opt for a player with a large hard drive, or digital media storage."

Of course, this is something that manufacturers have already picked up on – disc-based recorder stalwart Panasonic recently announced a range of HDD recorders that also offer VOD services.

DVD recorders would only really continue to sell in Japan, reckons In-Stat – the same place where Blu-ray recorders are most likely to be bought. So it seems the watch-n-wipe culture promoted by TiVo and Sky+ is yet to catch on in the Far East.

While the predicted shipment figures are good news for the Blu-ray Disc Association, it may be concerned by In-Stat's findings that Blu-ray is on the wane in China, where the more affordable China Blue High-Definition (CBHD) format is taking hold.

So In-stat becomes too optimistic to say that the DVD technology would be completely replaced in the next three years. But even though Blu-ray players totally surpass DVD, it doesn’t necessarily mean that DVD would die completely.

The difference in quality between DVD and Blu-ray is nowhere near as extreme as the difference between VHS to DVD. Blu-ray excited people for its large capacity of 25GB of a single side and fast speed. That makes it to story more movies in high-definition and lately for 3D movies. With the help of Moyea PPT to DVD Burner it also enables users to view HD PowerPoint presentations on Blu-ray players. For that, it took DVD nearly a decade to overtake VHS in terms of sales and VHS continues for another 5 years afterwards before the end.

So even if Blu-ray was on the same situations like DVD had against VHS before, we cannot predict that Blu-ray could overtake DVD so quickly – soon after 2015, but around 2020 at least.

Since the technologies are always proceeding, newer technologies may come out in the long run. Blu-ray has to prove itself before it becomes the next true dominant format.
