Thank you for this post this is the 1st I hear of this roadmap.
These multiple hardforks are not only stressful on developers but its creates short-term uncertainty among investors. Even though they think it will provide multiple streams of positive news it can have the unintended effect of the market dropping because of the fear.
The devs did not talk about the price. Updated the post to clarify that. I think it would be good news because everyone is waiting for Metropolis, so having it come in stages is a welcome change instead of releasing the entire thing later.
I agree doing it in stages makes sense.
