PS3 sales 165k in two days in UK - but what does that mean?

In two days, 165,000 PS3 units have been sold in Great Britain. Record breaking, they say. Kevin and I decided to test that theory, but seeing what happened in Japan on the first two days, both comparing the sales figures, population of the two countries, and number of games at the launch.

Population:
60,609,153 (UK) is 47% of 127,463,611 (JAP)
UK has almost half the population of Japan.

PS3 Hardware Sales:
81,639 (JAP PS3) is 49% of 165,000 (UK PS3)

Launch Titles:
However, the PS3 launched in the UK with 22 titles, and only 5 in Japan. 5 is 23% of 22.

There are two theories to this:

1. The UK sales are a product of having more games, and this makes the UK sales figures less impressive.
   
2. Same as the above; however, this shows that the PS3 still has hope if it just gets enough games, because games drove the UK sales.

Background Data:
UK sold about 51% more PS3's than Japan did in its two day launch window. In order to match the UK sales, Japanese gamers would have had to buy about 84,150 more PS3's; however, that doesn't take into account there are twice as many Japanese, just how much it would take to make each country's sale ratios equal.

If UK has half the pop of Japan, and bought half more PS3's than Japan... then that would mean that Japan would have to by TWICE (100%) more PS3's to match the "Desiration Factor" of the PS3 in the UK. We aren't factoring in price, because while we think the UK PS3 is more expensive than the Japanese PS3 (British pound versus Japanese yen), we're not sure.
