Those box art covers have actually been out for quite some time now too.
What dampens my hope in possible remakes being released, at least for this generation, is the number of Hoenn Pokémon being available in Black 2 and White 2, especially the Legendaries like others mentioned before. It also makes me wonder if what some have been predicting before, that GameFreak will instead do a remake of just Emerald rather than both Ruby and Sapphire. If they were to do this, then I wouldn't particularly be upset about it. Emerald did have the better storyline of the three, and I can see them being able to do a lot more with it in a remake than if they were to fix up the storyline in Ruby and Sapphire.
Also, that's a really cheery remix of the music from Rustboro City. Yeesh!
