Early adopters of any system are always the losers one way another, I don't see this situation being vastly different.
If you are an early adopter you pay more, often substantially more, than later adopters. You have a limited selection of games, poorer OS features, bugs, game droughts, noisier louder systems etc. etc, All things that we aware of but we accept as the price for being an early adopter. The late adopter of any gaming system (often not even fans) pays less, gets more reliable hardware, starts with all the features, has way more games to chose from including budget games and is given a better overall experience. Some things such as software/firmware are improved for the early adopter as well but they never get back the premium they paid for the system or get to swap out their old fat system for the newer, slimmer quieter one.
So far we have one exclusive game announced for the New 3DS and I can't see that changing much until Nintendo sells alot more of them. What's more it's not even an exclusive game, it's a remake. Otherwise what we have is a mid-life hardware refresh like any other. If it matters to you, poney up the dough, otherwise be satisfied with the system that when you committed to buying you knew was, sooner or later, going to get superseded by something shinier and better.
