Here are the reactions of some PC-Engine developers when the NEC SuperGrafx was demonstrated in 1989.

Since we are at a time where we don't understand the system very well, we cannot say anything.
NEC Avenue
A machine without excess fat. Development will be interesting. But the machine's appearance...
Sunsoft
The price is slightly strange for something that only increases the amount of RAM. I had expected more secrets in there.
Taito
It's too early to comment. We hope to make games that use its powerful graphic functions.
Data East
Since we are at a time where we don't understand the system very well, we cannot say anything.

Since it's early, it [SGX] is like a sheet of blank paper. But in terms of graphics, the current PC-Engine is good enough, I think.
Namco
We will watch the market calmly for a little while. We will enter [the SGX market] after considering it well.
Nichibutsu
Since the SGX is downward compatible with the PC-Engine, we are developing software aimed at the current PC-Engine.
FACE
Since the current PC-Engine market is growing, for the time being, we are concentrating our resources on the present PC-Engine.
Hudson
Since this is a big brother to the PC-Engine, it gives software houses a good chance to try. Development pays the maximum reward.

And now, it's time for another round of "Lukewarm software company reactions to new NEC hardware Announcements!"
This time we have reactions from companies when the [even more unnecessary] PC-Engine Shuttle (¥18,800) and CoreGrafx (¥24,800) were demonstrated on 12/8/1989.

We were a bit worried about what the retail price was going to be. As for software, we will look at the situation for about half a year and then consider it.
Naxat
The Shuttle is good for new users. I expect it to be flexible. Our company would like to make 2 or 3 games [on one card(?)] for the lower age group.
Namco
We will watch the Shuttle with expectation. Especially for the moment, compatible software is not being considered.
Human
Even though we are glad the number of users is increasing, we will carry on with our projects as before. We are not considering it, especially. We had hoped that the hardware would be a bit cheaper.
Hudson
The Shuttle is perfect for the user who doesn't want to try CD-ROM. We want to make some software for these new users.

Just look at that enthusiasm!
