I don't want to be too harsh on the design team, but I'm disappointed at the lack of innovation as well. For an update that is literally called 'Ships', I was expecting more genuinely new ships than just the Corvette.. it's not that I object to variants of existing ships per se, but when five of the six ships being released are essentially variants, that's a bit much.
At the very least, I thought that the Keelback would be a unique design, because it has a unique name... as it is, it would make more sense to just call it the Type-6 Mk II. In fact, why isn't it called the Type-6 Keelback? Just calling it the Keelback alone makes it sound like a completely different ship, when it really isn't...
Likewise with the Cutter - it is not actually meant to be a variant of the Clipper, so there was no reason for it to look so similar at all. If instead they had made it resemble the Interdictor, like the Corvette resembles the Farragut, that would have been great; but instead it might as well just be a Clipper Mk II, in terms of appearance at least.
And as for the Asp Scout? I'll be honest, I love the Asp's classic design, but the question that keeps nagging at the back of my mind is, do we really need it? We already have the Asp Explorer, a good ship that is ideal for exploration; and the Diamondback Explorer, also ideal for exploration; and the Diamondback Scout, which is ideal for exploration as well; not to mention the Adder, which makes for a good explorer too; and the Cobra Mk III, which can explore with the best of them; and even the Lakon Type-6, for explorers who like to be a little different. And to this lineup of similarly-priced ships, we are now going to add the similarly-priced Asp Scout, are we?
...Why?
Call me crazy, but I think it would have been better for Frontier to add a bunch of new ships in 1.5, and save variants like these for next year. After all, the focus next year will be on Horizons, and the players who paid for it; so if these exact same ships had been released next year as a surprise free update for ALL players, I'm sure they would have been very well received, and no one would have been complaining that they were just variants because no one would have been expecting them anyway. But, as it is? Well... unless there's a lot of stuff that they are not telling us, it looks like 1.5 might barely even be an update at all...
