That is actually a fairer price than the offer on the same model here, that is 899 last week (and is ongoing). Sure, you have -3% VAT-DE compared to VAT-IT, but this does not explain a 14% difference in price: as I suspected, you definitely have better deals on SP4 in Germany than where I live... Good for you!
However, does that offer include the SP4 keyboard? Here it doesn't! So I would have to add € 111 for the regular one, or 164 for the Alcantara version (the one Eve-V will come with). That would bring that offer to around € 935, at your price, or around €1050 at IT price.
In Europe, the Eve-V m3 with an ISO-variant keyboard included, should have cost around 839-847 Euros (hyper early - early bird prices), including all shipping costs and taxes, correct me if I am wrong. I don't want to contradict your math, but I genuinely fail to see a price match...
Shifting to the hardware components comparison you made, it's a little bit tricky to campare this specific SP4 variant to the Eve-V... With the core i5-u/6gen you get the ability to hold bursts for longer, no significant variation in bursts clock speed and a... fan to cool it down should you effectively use that extra power (however, in all fairness I read somewhere that the SP4 i5 it's less prone to activate the fan compared to the i7 SP4 models). The m3/7gen should grant a little more power efficiency when in idle (6th vs 7th gen).
You also get only 4Gb of RAM instead of 8Gb, which alone makes it quite unpleasant to me: RAM is cheaper than a SDD space increase and even cheaper than a processor step up, so in 2017 I feel like being tricked when a vendor is offering me to buy a 900+ Euros computer with 4Gb of RAM.
To me, honestly, this is not a clear win. Personally, given the choice between the two, even if the Surface did not cost 90 (DE) - 210 (IT) Euros more as it actually does, I would still choose the Eve-v m3. I will acknowledge that I might be slightly biased, though ! I would understand if someone made the opposite choice based on its preference, anyway; a little less so with the IT price difference...
Finally, as I said, I really see your point. If Eve prices will go much higher after campaign, the second most important advantage of the Eve-V (which is price competitiveness) will fail or be washed-out. However, I do not have info on these "higher prices" and honestly I don't think the Team themselves have fixed those post-campaign numbers as of today! It seems a little premature to worry about this now, but your point is true without a doubt! All in all, I maintain a fair optimism on this issue, because Eve track record on prices has been nothing less than excellent, until now.
To me, right now the most worrisome issue for Eve is the last one you mention: the timing they will be able to make a fully tested and flawless V available to the public. The earlier the better, because the market will be flooded by competition this year and they will have to find buyers mostly outside their community (which as you guess, it's their first and quite unique strength ).
