Extended seems possible. Target/Wal-Mart are always selling old product bundled with newer sets. At least if Extended was available, some players wouldn't lose their top when the new cool promo is bundled with a few older packs.
Worst of two evils: must draw 4 prizes or can win by only taking one prize. The way I see it, a player can lose normally in swiss (or game 1 in top cut) if they get first turn donked or time (+3) ends with them 6/5 (prize ratio). Why is it frowned upon for game 2 in top cut? I'd rather the game ends normally (by donking, up on prizes, bench out, deck out) than institute artificial rules (must takes 4 prizes to get credit for win) in order to deter short game wins. Short games are part of the game, and we see them all over Swiss and in Top Cut (Masters, Nationals 2010, Finals, Erik Nance donks Con Le).
TPC changing the use of Rare Candy is going to deter Stage 2 Donking a bit, like for cards like Jumpluff HGSS or Kingdra Prime UL. Perhaps with no Shuppet or Uxie in HGSS-on, there won't be any more T1 Donk.
Time limit-wise, I agree with Kwisdumb that the game is growing and in a few years, States and Regionals will be 2-day. That just seems the obvious path to me, and the only way it won't happen is if the people with power force it not to.

One massive problem I see in the game is that we are playing a totally different format than Japan, the country where the game is originally made.
Japan's format is now HGSS-on. TPC will be designing cards to fit this format.
Our format (now) is MD-on, and even 20 months from now, our format will not be HGSS-on. That's a good 5 sets that will potentially not "mesh" well with our format.
We worry about donk, and it seems with the release of cards like Seeker, uxie/shuppet donk is getting a bit better. Players in Japan don't have this issue because Uxie/Shuppet aren't legal in HGSS-on format.
Any decent cards that are released between now and September 2011 are going to help SP decks only become more dominant. Japanese players don't have to worry about this because there are no legal SP cards in HGSS-on format.
Do people realize how far behind format-wise we are with Japan? It will take us until September 2012 (if TPCi follows the standard set rotation cycle) to get back on track with Japan's format...which may be different by then!
Let's not even start the discussion of TPCi manipulating the Japanese sets to produce extra/less products. This throws the progression off all together.
I wouldn't be voicing this concern if the world didn't gather together each year at the World Championships and play the same game. Because we do meet up with the Japanese at Worlds and we do have to worry about the ramifications of TPCi's actions within Japan, I feel there are problems with trying to play a "translated" version of the Japanese Pokemon TCG that isn't the same game, with the same formats, and the same cards available.
