In the words of Joel Robinson, "What do you think, sirs?"
Top Dollar Amounts: I think they're fine the way they are now, but I wouldn't mind moving $5,000 to Round 3 and making the top dollar amount in Round 4 $7,500 in a few years.
$1,000/$1,500: I definitely agree that we need more spaces higher than $900 besides the Mystery Wedges. $1,250 and $2,000 would be nice to see again.
Toss-Ups: Your method of Toss-Ups isn't very fair. If they have one before Round 3, then that means there's a chance that one player will never have the chance to start a round.
Prizes: More than one prize would be nice, but we have Prize Puzzles, plus the yellow $400 where the second prize used to go is now Free Play. I don't think we need anymore tokens and wedges on the wheel.
Jackpot: I do agree that it was better as Round 2. If they're going to leave it as Round 1, they should at least do SOMETHING with Round 2. Maybe a permanent Prize Puzzle round?
Bankrupts: I liked the way they had it last season, but I would put one in Round 1, two in Rounds 2 and 3, but still have two in Round 4, but not next to the $5,000.
Safeguard: See "Prizes" statement above. "Invincibility" would be a better name anyway.
Credits: Agreed. The older credit plugs were better and didn't feel like a quick commercial break and then come back only for the credits.
Classic Theme: As much as I like the classic themes, it would seem a bit out of place, like the Combs Feud theme on the current version. Maybe a new CK arrangement?
