Options 1 and 2 are the result of appearing at a prominent position in the app store being largely based the less than optimal way apps gain the prominent position. Apple needs to find a better way to make the good apps more easily findable to avoid what amounts to a landrush in the app store. Whenever anyone is thinking "I can get by without doing a good job and I <i>need</i> to rush through something", it doesn't lead to a good experience, for consumers or for developers. Let's hope the nice/good guys don't finish last.
A fourth option is to submit the app in advance, but release it to the store at a later time. On release date of the iPad, get one, drive home, test your app, and if it's running well enough, put it online in the store.
I've got a sheet music app for the iPhone (almost done) that really would be much more killer on the iPad: <a href="http://www.wonderwarp.com/opus" rel="nofollow">http://www.wonderwarp.com/opus</a>
Option 4: Be Electronic Arts.<p>As seen in the Engadget photo leak, some developers already have devices that are bolted to tables. So there will be some apps but from the big names only.
