CNET Australia's Ty Pendlebury has written a report from an LG sponsored trip to Korea with the very interesting news that LG is planning to sell 3D glasses for only AUD $79.

This is a much cheaper price point that competing glasses, which could cost up to AUD $200 each if the reported US $150 price point for Samsung's additional pairs of 3D glasses is correct.

Given that some 3D TV manufacturers are planning on giving away only one set of 3D glasses with their 3D TVs, and other manufacturers planning on giving away two sets of 3D glasses with each 3D TV sold, one thing is clear: if you have more than one or two people in your family, or plan on having guests over, the purchased of additional pairs of 3D glasses will be mandatory.

If you need to buy several pairs of glasses, the true cost of going 3D starts increasing relatively dramatically, over and above the need to buy a 3D TV in the first place, a 3D Blu-ray player and then 3D Blu-ray discs - or whatever the upgrade cost to access forthcoming 3D content on pay TV networks.

Unfortunately there's still more detail needed on the exact specs of LG's 3D glasses.

Panasonic's 3D active-shutter glasses are supposed to be polarised, whereas the 3D active-shutter glasses that Sony will offer with its 3D TVs don't need the polarisation.

Will LG's be polarised? Will they work with any brand of 3D TV, or 3D projector?

These are questions that will clearly be answered in the course of time, with LG simply signifying that it too will be taking part in the 3D revolution, even if it has delayed its consumer range of 3D TVs for the time being, concentrating on the commercial 3D TV space to start with before presumably launching their own brand of consumer 3D TVs either later in the year, or presumably some time next year.

At least LG's price point puts immediate price pressure on every other manufacturer to drop the price of 3D glasses, although whether it will make any immediate difference to the upcoming launch of 3D TVs in Australia and the price of same-brand glasses is yet to be seen'¦ so to speak.

Another thing is certain: the first generation of the current 3D TV technology will soon be supplanted by a second generation, with prices next year surely lower than prices this year.

Unless you have tons of cash to burn and must re-watch Avatar in 3D from November this year, stick with your trust 2D set for now, and jump on the 3D bandwagon once the second or even third generation has arrived.

Waiting for next-gen technology means an agonising wait, but who doesn't want better 3D value for their 3D dollars?
