I just want to point out a few things:
WickedLasers now advertises all their lasers by the max and min power. The "300mW" E3, for example, is "150-300mW." The 1W Spyder will likely be "500-1000mW." That leaves a big, ambiguous, 500mW hole that you can fill with your hopes and dreams.
Secondly, 1W peak portable 532nm lasers are not impossible to make. Sustaining that power is the hard part.
When WL first introduced their 2010 series lasers, they had for sale a 400mW Spyder III. A few members here received some units to review and one peaked in the 700s.
On top of that, long ago I owned a 400mW PGL-III-C from CNI that peaked in the 800s and sustained >650mW, so I know it is possible to produce absurdly powerful portable DPSS greenies today. My guess is that CNI will be the primary manufacturer of the modules that WL uses. The most likely scenario I foresee is that WL asks CNI to manufacture a batch of >500mW modules, in which case anyone who buys the 1W 532nm Spyder should expect a >500mW laser, not a >1W laser. But that is just speculation.
Which brings me to my last point - maybe they will make a great laser, maybe they won't. Until something is actually produced, there is not really any point discussing what we think it might be.
