Maybe, but I'm not sure there is the same demand for characters. The ships are unique to Star Trek, you don't really see anything that looks like those in other franchises. Once you start putting out multiples of people in the same colour uniform with different heads, the incentive to buy becomes much less, at least in my opinion. I mean, hold up a Tom Paris figure next to a Chakotay one - the only defining feature is a different head, that would be lucky to be a centimetre in size if they follow the Marvel format. Superheroes have full body designs and usually have signature poses. Star Trek has... pyjamas. I'm sure they'll give it a shot, I just don't expect it to fly off the shelves.
You've got a point but I think if they spaced out the ones that look too similar, they'll be OK. And some characters - Kirk, Spock, Picard, Data, Worf etc - will do well regardless. As for the others - intermix them with Ferengi, Cardassians, Xindi, Gorns and so on - and I think Eaglemoss would be on to another winner.
Are there any ships from the collection that u aint sure about getting?.for me it the borg sphere,bajoran solar sail and the krenim temporal ship.
The completist in me wants them all, but the sane father-of-four-on-a-budget is approaching each release cautiously.
There's plenty I'll skip (at least for now) - if I find those particular issues cheap in the months and years to come, might pick them up. The three you mention are low on my list, as are a lot of the post-issue #25 ones we've heard about...
