This kind of thing is happening irl thus will affect into this system as well because many people earned tc by buying packs and such so if it is overpriced some people will stop buying it and tcs distribution probably will slow down a little, but it has a bigger effect later in the future.
Boosters and packs price are keep increasing on certain country:
The beggining of 2009 boosters price increased by $0.95
Around june 2009 increased by $1.00 (on my country its increased by $1.5)
If I remember correctly in September to November 2009, again, the price increased by $1.00
This might not affect people in America and its surrounding but its a big impact for people at eastern area of the world, especially because around february 2010, Asia got a money crysis.
To sum it up, it may happen. And because i live in Asia I prefer to saving my tc. :3
