this example from last June, a few words followed by the press release. Not so much a splash.
It just didn't stop there. There was then some trickle of info on when it would be sold, followed by some bit of material here and there that it was on sale in the US, followed by online shortages and in-store general lack of availability, followed by a semi sort of almost announcement that it was now discontinued in the product line/no longer planned on being produced. Besides various reviewers, gamers, musicians, RB3 players and those here on the forum, who even knew about it?
Some might say that when you don't advertise much and you don't have Amazon directly sell a product, you're worried about something. And that something likely isn't sales.
Hindsight is always 20/20, looking back is still a bit fuzzy. The game specific keyboard, drums and guitar controllers for pro might have been a factor for me to buy at release, if the RB3 Squier had never existed. But since it does exist? If I had known how the game was at release, how the MPA situation was going to go, and how the RB3 Squier situation was going to go, I might not have gotten the game until I had two MPA and the RB3 Squier.
From the retail side of things, what was the main selling point? Let's see
RB3 has great new party modes for quick rocking sessions with friends, as well as a whole new universe of challenges including a revamped Career Mode and 700+ goals and rewards
Game track list contains over 80 of the best bands from around the world, including bands that have never appeared in a music game, and support for existing Rock Band tracks
Create and save set lists, and share them with your friends online and enjoy improved song sorting makes it easier to find the songs you like
Expand the band with the optional keyboard peripheral and 3-part vocals harmonies, together allowing support for up to 7 players
Take your passion for music to the next level with Rock Band Pro functionality that lets you develop real musical instrument skills through gameplay
Doesn't seem to be much of one in particular.
HMX has been doing everything correctly. Astounding. It just seems like they got saddled with business partners that have been less than fantastic, which has affected other things that are not their doing or have no control over. Legal issues aside though, it seems rather foolish for anyone business-wise to badmouth anyone else. Of course, the problem with that is everyone sees the truth anyway, and shutting up about it just keeps the status quo in place.
As far as the Mustang goes, there are benefits and it has its uses. Could be very helpful. Easier to get certainly and it's also less expensive, around $100 used. But it's not just you. No mater how close any "simulated guitar" is to a real guitar, it's not one. It may be almost exactly the same but for the physical differences between buttons and strings for the fretting hand, somewhat similar in concept to how it's possible to play bass guitar on a non-bass guitar; The same, aside from all the tactile differences and technique modifications and physical changes.
